I'd like to stick with single layers.
At what ratio do you guys feel the movie is being compressed too much and make the jump to a dual layer disc?

anything less than 50% is going to look bad.i like to keep mine around 70% quality. if u dont want to spend the extra cash on dl disk for the larger video u could try dvdrebuilder with CCE. hc (hanks encoder) is a free encoder that works well. u can get the basic dvdrebuilder for free too.

It's all personal. First things first, I always remove unnecessary audio and subtitles. Anything above 65% is fine with me. From 55%-65%, I'm looking to get rid of the audio commentaries, but only if it's a movie (or film maker) I don't like. From 50%-55%, I'm looking for anything to do to get it up to 60. If it's something I really like, say Seinfeld or 24, i'll have to burn it to a DL. If it's below 50%, and I really like it, again, DL. If it's something I don't particularly like, I'll just rip the movie.
Of course, I always have deep analysis and smoothness checked.
Latest AnyDVD to rip > VOBB to blank the unwanted on a DVD > Shrink to compress > ImgBurn to burn = Never starting a thread asking how to backup a movie

I go a bit farther..... The quality must be around 80% or I use the best encoder--DVDRebuilder with CCE! I do movie only.... don't want the directors comments or commercials or warnings! I use DVDFab Platinum unless quality is less than 80%.

90-99.9% - Max Sharp
80-90% - Default Sharp
65-80% - Smooth
<65% - Max Smooth
These are the suggested rates for DVD Shrink in a guide from Digital Digest, they can also be applied with Nero Recode as this is the same program. Using CloneDVD I do not go more than 80% then I use another program. I too use DVD Rebuilder for higher compression movies it is an excellent program and the quality is unmatched doing large compression. If you are going to do higher compression it is best to use a program like Shrink or Recode because you can do a deep analysis, which make two passes to get the best rate of compression and then use AEC settings accordingly. Just my two cents :)

And then there's always splitting to two SL disc for 100% reproduction and no compression.....

I hate spitting the DVDs up to two discs! I even have a 5 disc changer and I still hate to spit a movie to two discs!

I don't mind splitting serial disks. I like to use Clone and preserve the menu but only have two episodes of an hour program. I split all my Sopranos, it makes for more disks, but no compression. And I usually do not sit around and watch more than a couple at one time anyway.

If one does not like to split discs, then one shouldn't do so, BUT, that does not mean it's not a useful option for others. And, it's a lot cheaper than DLs.....

If one likes more discs then one should burn more disc..... this guy's not stopping anyone from doing what they want! I just added my 2 cents worth..... can you give me change? hahahahahaha

For me my ratios are more like Mr_Pink and i do the same thing as IHOE and use rebuilder pro when i cant get up to 65% or so by eliminating things. Ive got CCE with it also. Rebuilder Pro is a great program and always updating.

My 2 cents: I usually burn only the movie and eliminate most sound tracks so that the compression ratio is as high as possible.
In some cases I had to go down below 60% (for example, if you shrink a DVD of one of those TV series like "24" or "CSI" that have 4 episodes).
I only use DVDshrink, cause I'm lazy.
In some cases I can notice the pixelation. It does not bother me, but this is a matter of personal preference.

DVD-RB Pro/CCE has spoiled me as no other compression app can compare to its video quality. A little more time and a few extra steps are not a problem for me to obtain what I know is the best video quality possible compressing to only 1 dvd5.

Here is my rule of thumb:
Most DVDs: Compress movie only with still menus (MenuShrink) to DVD5
Rare DVDs: Split to 2 discs or Compress movie only with stills to DVD5
Sony Movies: Remove every special feature on it and fit it on a DVD5
Good Sony Movies with good special features: Split to 2 DVD5s
Porn: Remove all extras and cut some video and compress to DVD5
-Split to 2 DVD5
-back up to DL if it is rare and/or expensive
Why I say this:
Most DVDs have a reasonably good bitrate to begin with. If a movie only will fit on to a DVD5 with reasonable compression (55% or more) then you will get almost identical quality to the original.
Rare DVDs are expensive. Think of these as Criterion and such. If it is an out of Print movie, split to 2 discs, or maybe even back up to DVDrDL. If something happens to the original, there is no way to restore a compressed back up to the original, since MPEG-2 is lossy. However, these movies will not lose any quality when backed up on a DVD5 movie only with still menus. It is up to you.
Sony Movies: Sony uses the lowest bitrate I have seen on movies. Stealth for example is about 3500kbps bitrate, which represents about 26% of max and a compression of about 70:1. Further compressing can lead to quality problems.
Good Sony movies w/extras: Sony usually puts tons of extras on a DVD. If you really like the extra content, then you should split the disc to 2 DVD5s. Using a DL will be a waste of money because these movies are usually not expensive from stores and DLs will give you more bang for the buck for rarer movies. Compressing these, may give bad results. Say you considered Stealth a good movie and wanted to keep all the extras. You would probably compress to 50% or so, which would take the overall compression to 140:1 and give a bitrate of about 1750kbs (about as much as a good sVCD). This will give a high probablity of occurances of motion artifacts and such and you may not enjoy the movie the same.
Porn: Porn is not recorded with the same cameras as hollywood movies and there are no computer generated effects. This means that you are presented with something of sub-par original quality. Also, porn always has lots of motion, otherwise it is not good porn... Another thing is that porn is usually over 2 hours and generally 150 minutes or more and also includes a good amount of extra content. If there is too much motion everywhere, encoders will have a hard time dispersing the bitrate. Also, since the length is so long, it will require longer GOP structures and a lower bitrate. This will lead to motion artifacts everywhere and a pointless backup.
Removing the bonus material and some scenes will take the compression way down to 75% to maybe even 80%. This will significantly improve quality and make for better viewing. Splitting to 2 DVD5s is easy to do with Porn, since it works like seasonl discs. You can choose to have 3 scenes on 1 disc and 2 scenes + bonus material on the other and so on. If anything happens to the original, this can be later restored to a DVDDL for full quality on a single disc.
Some porn is very expensive and can be anywhere from $35 to even over $100. Generally, good porn is $35 to $60. This is far more expensive than any DVD except for incredibly limited DVDs (Appleseed Limited for $60 for example). Combining discs cn sometimes lead to problems depending on how they are authored. The best free way I can think of doing it, is ripping with decrypter in IFO Mode and splitting by chapter (not cell) and then using VobBlanker to replace cells. I do not know if it will work, but it should. Otherwise you would have to re-author the DVD and that can be tricky, especially to get the original menu back.

@JaguarGod,
You are a wealth of information. That was a mini-essay there and very informative. Even included porn. :)
