Why doesn't Shrink Rip the file on Advanced Analysis?

Why during the advanced analysis in Shrink is the file not ripped to the HDD? In other words when the encoding stage of the program runs, it reads the DVD again. Thus putting double the mileage on the laser. Wouldn't it be quicker if the recoding would be done reading the file off the HDD. Nero Recode of course does same thing. Just wondering.

i know from my experience that when the movie is on my hdd it ALWAYS goes faster than my dvdrom. i just load em in with the fab and reduce em with shrink. at any given time ill have 10 or so movies on my hdd, and it does go a LOT faster vs. my rom..for example, a movie on my hdd will analyize in 30 minutes vs my dvdrom @ 45 minutes. the movie on my hdd also encodes around 20,000 to 25,000 kbps vs. the rom @ 15,000 or so kbps....to me, the hdd is quicker

Why not just rip the disc to hdd with DVD Decrypter or Dvd fab decrypter
Then run through Shrink--Thus using the laser to rip and burn only!

yeah i agree with Co45. Thats why I bought another dvd drive just to rip and save the life of my burner. I bought a Lite-on I belive there are the best they are quick and the ones with smart ripping technology which mine has pivots the laser when reading to get around scratches or other disc imperfections. The reason shrink is very similar to Nero is because the man how designed dvdshrink was hired by Nero to design recode and other programs. If I remeber correctly that is also why there is no more updates or someone was theating law suits, well it was probably both.

@ Co45, slmh1296,
I believe garmoon is using AnyDVD with shrink and thats why garmoon is not ripping to the hdd first.

You are all correct. The encoding will go faster when done from HDD. So why when Shrink or Recode is doing the original anaylsis it doesn't it rip at it analyzes (it seems to read the whole disc) so when it does recode it; it does from the HDD? I know I could rip it with AnyDVD or Decrypter, but since Shrink and Recode are already reading once, it seems like it could rip too. I don't want to skip the advanced analysis stage or the slow encode stage of these programs. There's got to be something with the software that prevents ripping during the advanced analysis.
I've got three 16X burners and not worried about the lasers but more about the extra time it takes for a double read. I may have mislead in the original post.
I'll do a test: rip to HDD with AnyDVD ripper and Run Recode in a.a. and slow encode. Then Run Recode with AnyDVD in background and let it do it's stuuf and report back. Compare times.

Because the analysis is not a ripping stage but merely passes over the disk to determine the best allocation for space on the disk. After the analysis the disk will be encoded to that determination of space.
Quote:
What does the "Deep Analysis" do?
"Deep Analysis" does two important things:
It verifies that the output file size will NOT exceed the standard 4.37Gb limitation you have with a standard single layer DVD-R.
It greatly improves the output quality of the backup. What it does is analyzes each individual scene of the DVD, and decides how to allocate the bitrate (compress some scenes more than others.) so that the overall output quality will be better since DVD Shrink can apply the compression more accurately. (By no means am I implying that if you do the "DA", you wont have those artifacts or pixelation! I do a "DA" on every one of my backups.)
When using the "DA" feature, your backups will take considerably longer than before if you weren't using "DA". (Usually around 35 min up to an hour depending on the amount of compression that is going to be used and the CPU in your computer.)
If you are worried about this then rip the disk first with DVDFab or Decrypter and then you will not have this happen in the deep analysis stage.

That sounds logical.
I ran this comparison test with Harry Potter GOF 7301MB disc on 2 day old BenQ 1650 on a Dell 2.26 P4 with 512MB Rambus ram. Nero Recode and AnyDVD programs on C drive, Temp folders and rip folder on D drive beaucoup space both drives. I wasn't expecting the results I got.
1. I ripped the whole disc to HDD D: with AnyDVD's ripper time it took was 12'15". Nero Recode opened the file and did it's quick analyzing. about 1'. Whole movie to be backed up(62%compression). Advanced Analysis and Slow Encoding turned on and burn button pressed. Time till it asked for disc for the burn was: 50'42" Total time rip to start burn 63'57"
2. AnyDVD running in background. Recode set to do whole movie (all previous rips and files deleted) Again it took 1' for initial analysis(62%compression). AA and SE were again selected and burn hit. Time till it asked for the disc to burn was only 53'20". Total time rip to start burn 54'20"
The encoding process was quicker by less than 3'when on the HDD. Not much of an advantage. BUT the whole process, by not ripping first, was 9'37" quicker. I would have thought #1 would have been faster. I have been doing them the #2 way all this time and now I see it's faster on my set up. Only ripping first when Recode or Shrink crapped out or with scratched discs.
I assume Shrink would have taken slightly longer with both ways, since Recode is a little quicker.
If I do "Movie only" option my times are down to around 35-40 min, including burn, normally with less compression.
