My intention: Back up of "Cowboy Bebop: Vol. 1"
Software of choice: DVD Decrypter (version 3.5.1.0), VobBlanker (version 2.1), DVD Shrink (version 3.2.0.15)

I suspect the problem lies in the ripping process using Decrypter, because before I decided to use VobBlanker to remove some trailers, I was only using Decrypter & Shrink...When it came time to compressing with Shrink, an error message ("Invalid data in file C:\Documents and Settings\____\My Documents\Video\Anime\DVDs\Cowboy Bebop\VTS_01_0.VOB") came up, and the compression process was unable to complete.

I didn't change any of the default settings in Decrypter, by the way.

What happened?
