I do realize that the files on your DVD and those compressed and produced by DVD Shrink have .VOB extensions, but essentially they seem to all have a core Mpeg format. If you have Plextor tools you can have it analyze the disk and it will reveal this formatting. If you do you'll find that all non-decrypted, non-compressed DVDs are generally Mpeg2. Analyze the same disk after using DVD Shrink and compressing it, and it will show Mpeg1.
So far the only commonality of my DVD players failure are disks showing Mpeg1 formats (as determined by Plextor tools). I've been able to make a direct copy of a concert video which was not encrypted nor did I need to compress it and my TV top DVD player had no problems with it (Plextor analyzed the original and the copy to both be Mpeg2), so the problem isn't the burning software or the media (DVD-R is the only type this old player will use). I do need to experiment with Shrink to see if it will produce non-compressed decoded backups that will work. I'm wondering if the problem is in the compression and the resulting altered files.
Also, anyone have any experience with Roxio? Keeps giving me a "non-compatible media" message when I try to burn with DVD-Rs (or any DVD for that matter) from "create DVD" option. Probably need to get Nero, aye?
