OK. This initially came up because I was trying to rip a DVD for a video yesterday, but I've also noticed it happening with some other discs as well.
It seems, for some reason, certain Bandai DVDs don't seem to want to run in my comp (and, from asking around, I'm not the only one who's had these problems before)
So far I've spotted it on at least 3 DVDs (Escaflowne vols 5 and 6, and Zeta Gundam Vol 4)
The first ep will play just fine, but any attepts to play anything after that will either bump you back to the main menu or just shut off the player entirely.
Similarly, attempts to rip any footage from this area have had no luck (DVD Decrypter crashes at 1% and DVDMPeG will be able to read the VOBs, but the image is a garbled mess.)
Does anyone know what this is about? and to that end, if there's anything that can be done for it?
