I'm new to DVDShrink (looks very useful) and I read the guide that mentions a 50-60% result in the example, but I know you want to minimize the compression necessary by deleting everything you can stand to leave off.

For my first movie, it looks like I can leave out the English audio track (I'll watch it in Japanese with subs) and one of the 2 JP audio tracks (2-channel & 5.1-surround). The 2-channel audio is less desirable to keep, but it requires much less space -- would you usually burn with 5.1 audio even though it's a bigger chunk of real estate? I assume so.

In a general sense, is there a certain reasonable range of compression I should be hitting so my backups don't look too crappy, or does it just vary a lot depending on the movie? I know extras play a role, but I don't know how much video quality I'm sacrificing by, say, keeping a 80mb extra feature or prefering a 1,500mb audio track to a 700mb one.

Thanks for any general guidelines or tips.

There's not much difference on an untrained eye. I've compressed many movies 50% or even lower (double compressed). Played the movie on a 60" screen TV and could not tell the difference. There are other people that claim that they do see a difference. I may have untrained eyes, but a movie is not going to be any worst than some commercial VHS.

What is important is to keep the burn speed down and burn it on quality DVDr's like TY, and Verbatims. I'm sure you probably heard this alot, but stay away from Memocrap.

KCflyguy, when you say Memocrap would that be Memorex? I am currently using Verbatium but have used Memorex in the past

I have been making backups of my movies for about a year or so and occasionally have problems but usually say "OH WELL" then when I downloaded AnyDVD I thought I had it made but now I am running into problems again my most current is DARK WATER. DVDShrink gives me an "out of memory error", so then I put it through DVDencrypter and it did its thing, but when I put the movie back into DVDshrink I get an error of "invalid data in file".
The pc I am using has a AMD64 x2 processor with 1g ram and 250g harddrive, the burner is a hp 740B ED24, the DVD player is a IDE-DVD DROM6216 DH08. I will continue to read through the forum for more information on issues that I have had or have. But if anyone has a remedy for my issue with DARK WATER I would appreciate it.

Shoot for 50%+, preferably 60+. The higher your percent, the less is being compressed. On some DVDs it doesn't make much difference, but animated series and TV shows can suffer a lot below the 50% line.
