Thanks for the positive feedback, Sophocles.
I'm about to backup "Face/Off" R1 with v3.2b4 and IC8.
That should also be a good test.

One thing I can say about a 4GB variance: when the burner is writing the closing of a disc, it can prevent it from happening. I've gotten a coaster from playing too close to the limit.

I've never had a problem going to the edge. With my first burner I'd say that's just because it's that good (Pioneer 104), but with the one I use now (Sony DRU-500A) I wouldn't buy that arguement. It's not a bad burner, but it's no Pioneer. My DVD-RB backups are almost always within 20MB of full and I haven't ever had that problem. I also use a different burning program than most people. I use RecordNow Max 4.5 because when I started, Nero (5.5.x) had some issues with DVD burning, depending on the exact revision you had, your burner, your standalone, and the phase of the moon ;) so I never even tried burning a DVD with it and I don't even own a copy of Nero 6.

I did have similar problems, but they were all entirely due to bad media.
With Verbatim Datalife+ or Ritek G04 Grade A I can afford to change my target size to 4,474mB with no problem. :)

DVD Shrink and Nero 6. I moved the adjustment into the red in the custom setting, just playing around with the compression settings. I put it back in auto, and the disk burned to the end and wouldn't close. The files were there and I could go into the files and open in a viewer, it just wouldn't open up in a player and the log stated the error was in closing. Guess I caused it, but it should have gone back to the safe zone when I changed back to auto. Never had that happen with Recode2 in Nero or with any of my other programs.

We've been through the media question many times. Datalife for a while was the same disc made for Memorex, Maxell and Imation. I have all 4 made by Ricoh, which I hear isn't a bad manufacturer. Haven't used the Ritek though. I use DVDIdentifier and DVDInfoPro to check the discs. I can also check the disc for any write errors or bad sectors.
Memorex has switched to CMC Magnetics, which I hear isn't one of the better discs. The 'brand' companies shop around from different manufacturers. So, the consumer has a hard time of knowing what is being purchased.
One of the nice things about DVD Shrink, after you burn a disc, you can load the burned disk in Shrink and the analysis will often catch a flaw if there is one. Makes for a quick test tool.

DVD Shrink is very strict in terms of what you "feed" it, and indeed works well as a quick testing tool.

I never saw that in the other guides. Do you put that in yours? Just have a section in there for the things Shrink can do besides transcode a video. Be a shorty, but that would be a good slot to explain about using Shrink as a ripper.

I hope you guys find this as boring to read as it was to do it. LOL
Here are the results of my rip file size comparison, used a type 5 DVD and did no picture quality comparisons.
DVD Decrypter
4,505,970,688
SmartRipper
4,505,970,688
DVD Shrink no compression
4,505,968,640
DVD Shrink 100% compression
4,505,968,640
Both of the no compression rips and the one with100% compression file sizes were the same. I checked my settings and then ripped with Shrink then again using no compression ripped the movie again and the file size was still the same.
4,505,968,640 w
DVD Decrypter?s and SmartRipper?s files were exactly the same but DVD Shrink came in at 2048 Bytes smaller.
Individual files that were different. ALL ARE IN KB.
DVD Decrypter DVD Shrink
183,298 VTS_01_0 183,296
1,048,422 VTS_01_01 1,048,574
1,048, 522 VTS_01_02 1,048,574
1,048,498 VTS_01_03 1,048,574
1,048,344 VTS_01_04 1,048,574
20,282 KB VTS_01_05 19,762
All other files were identical in number and size. I realize this probably doesn?t mean a thing.
When I ripped with shrink I used custom size for the 100% compression.

I intend to add quite a lot of new guides to DVDShrink.info when v3.2 Final is released, and might just include what you suggested.
Good idea, brobear, thanks.

Sophocles, I don't actually know what causes the loss of a couple of kilobytes.
If I had to hazard a guess I'd say DVD Shrink "cleaned" the files up a bit. :D

If you look at the files that were ripped by DVD Decrypter and SmartRipper you'll note that the VOB files varied in size in exactly the same way but with DVD Shrink they were all identical at 1,048,574 KB. At the end of the rip VOB_01_05 came in considerably smaller.
Vurbal had mentioned earlier that there was a difference in his measures of Ripping with Shrink using no compression and custom size 100%. I used both settings but no matter how I ripped with DVD Srhink the files were identical.

The new Shrink could be out within 10 days, I've been playing with Beta 6 and it seems to have resolved some of the "compress B more" issues, affecting I believe mostly action/motion. I've sliced some action shots from MI: 2 and compared it against the original, DVD Shrink, and DVDcopy2 and found it a very interesting comparison.
DVD Shrink was as always, a bit softer in contrast then the other transcoders that I compared it too, but that it also seems to have had the effect of reducing visual pixilation during action scenes. In many cases that might translate to a visual benefit. When blowing up the snapshot scenes of the movie, pixel blocks were apparent in the original and DVDcopy2 before they were in Shrink. The colors of both DVD Shrink and DVDcopy2 were good but shrink seemed to me more colorful. I took more snapshots and continued to compare and shrink continually showed less pixilation unless you looked really close then you can see the perimeter of the block blurred into the background. It?s there but not noticeable.
Because of this test I think I now have a hypothesis as to why DVDcopy2 looks sharper than the other transcoders in high compression. It increases the contrast on both the dark and light spectrums. The blacks are blacker and the whites are even whiter. The software edits the movie to compensate for contrast. I think all transcoders do that but it's their choices that separates us in what we think is better.
I think this is also what causes the white macro-blocs reported by a few on the internet with DVDCopy2. Older movies with older FX such as the sparkling water effect used at the beginning of Splash, or other bits of snow introduced as a result of poor handling, are not recognized by DVDcopy2 as a part of the original streams and they cause the problems. Because the anomalies are not recognized as a part of the original content they could confuse the algorithmic structuring process and they aren?t compensated for. In affect the unwanted video/audio content are mathematically unaccounted for. Just a hypothesis of course.
I think it's mostly a tunning exercise as to which trasncoder is best, and you decide which you think is best. In the event that you cn't tell I'd go for free.

Your post would have been appropriate for both threads as your findings are about transcoding tools and not just about DVD Shrink. Shrink is just one of the players, albeit an up and coming one with its improved version. I think there are probably several other threads it would be appropriate for.
I'm glad someone with your technical skills and background took a closer look at this aspect of recording. Glad to see that I wasn't hallucinating.

A mysterious call in the night disturbed the slumber of the poor old Bear. I'm going to teach him its not nice to play with the bears. Just kidding, I love pestering BigO.
I noted in the other thread that everyone should take the link and read your post. Adds a new aspect to the question of 'whats under the hood' and how it was tuned (algorithm and compression tuning).

I just did a backup of Heart in concert. Its not a recent condert and as you all know older concerts were filmed using 3/4 inch beta cams. Although they're the best video cam of its time, it like all taped video suffered from low resolution and video noise such as white clipping. DVDcopy2 completely wiped out on this one, in fact I'm going email some screen shots to Intervideo and let them know about it.
If they can't find a fix then I'll consider posting the same shots on the internet. The compression was only 15% and DVD Shrink handled it with no problems of anykind. So for you folks out there, if you're using DVDcopy2 as your main transcoder then you 'd better keep a copy of DVD Shink on had for those older movies.

Have you finally had an occurrence of the dreaded pixellation problem with intervideo?. Or is this some other problem that has arisen?
Thanks in advance.

Not only have I had a problem but read my previous post. It wipes out on older movies that introduce noise to the stream

Damn it thats rough!!. I would be very interested in seeing some of those screen shots, to compare with the ones that I got.
Sophocles, you will be lucky to get a response from Intervideo. From my experience their technical support is a joke. I wish you the best of luck.

I already received a response and they sent me instructions for a fix that made the entire application crash. Trust me they don't want to get on my bad side.

I'd say any real solutions will come out with DVDCopy3 and everyone will have to pay for it. Seems to be the pattern so far. Maybe we'll get lucky. Hmmm...

Sophocles kindly sent me a few "stills" from this offending title. The pixellation exhibited can only be described as an "extreme" example of the phenomena that I suffered with a number of my titles.
Considering that people are spending good money on this software, I find it totally unacceptable. It, honestly, depresses the hell out of me.
