VOB files and incorrect playback time

[Pootle]

Hi,

I'm in the process of transferring all my blu-rays and DVDs onto my media server, and impressing a few friends with Mezzmo along the way...However I am having one problem with VOB files, and wondered if anyone else had come across this.

I've ripped close to 100 of my DVDs to the server (as combined/merged VOB files), but about 25% of them show a short play length (ie Finding Nemo is just over 6 minutes, Raiders of the Lost Ark is 57 mins). They all start to play fine, but after a certain amount of time it stops playing and returns to the menu. The time varies according to the DVD, but each specific film always stops at the same time.

I have ripped using DVD Shrink with settings so that it produces one large VOB. I've also used it to rip several 1GB VOBs and then used VOB Merge to combine, but the same thing always happens. Tonight I'll try RipIt4Me to see if that makes a difference, but does anyone have any ideas?

I'll try using VOB2MPG to convert to MPEG tonight, but I'd prefer not to have to do this as it makes the process much longer

Thanks
