Backup - reauthor/shrink problem

[trimicada]

Movie in question: Harry Potter - Prisoner of Azkaban

I used DVD Decrypter to decode to my hard drive. Then used DVD Shrink (3.15) to reauthor and burn ONLY the main title, no extras. Then tried to watch it and noticed multiple points (consistently starting about 20 minutes into the movie) that the video became jerky/jumpy/pixelated.

I assumed that it was a bad burn (or bad media). So I used DVD Shrink again but this time only encoded it to the local drive - I did NOT burn it to media. Then I used WinDVD to view the results and the picture was still jerky. So, not a media problem. I then opened the original files as decoded by DVD Decrypter with WinDVD and those files play perfectly.

I updated my version of DVD Shrink to 3.20 and tried again. To the local drive only, no burning. Same problem with the video. So then I tried Clone DVD - same problem.

Any ideas on why I cannot successfully get this to work? I am selecting the main title only each time...no extras, no extraneous audio - just the main title. If both DVD Shrink and Clone DVD have failed, is there another tool I can try?

Thanks.

I backed this movie up for my wife....same thing...movie only with DVDShrink...no problems.
Bad rip maybe?

I had no problem doing a movie only backup of this one, so I don't believe it is a protection issue. I can only suggest you rip it again and see what happens.

Ripping does not affect quality in any way.

What im more concerned about is the setting in dvd shrink. What is the dvd output size when compressed. Does it end up at around 4.37GB.

He has already said it happens on the HDD before the burn, and starts about 20 minutes in. That pretty much rules out media as the problem. It would be a fair shrink (although you can get back 10 minutes by killing the end credits), but well within Shrink's capabilities.

That's the only thing to try at this point I guess...re-rip with DVD Decrypter. Though those files do play fine when opened with WinDVD.

Yeah, haven't killed the end credits yet. But even so the % is 60 or 70%. Not the worst I've done and should have been OK.

Update: Finally got a successful backup. I had tried re-ripping using DVD Decrypter and then using DVD Shrink again, but had the same problem. So I then tried using DVD Shrink ONLY. And that was fine. Confusing because I've always used Decrypter first (out of habit because it's how I learned at first). This is the only time I can remember where I've had a problem like this. Guess in the future I might skip Decrypter more often and use Shrink directly.
