I've used VOBtool 0.0.6 for awhile now. You can find it at Download VOB Tool 0.0.6 - A tool for analyzing, joining and deleting segments from VOB files - Softpedia. If that link doesn't work - let me know - I can email the file to you - or is there a place to upload it to on this site?
It also opens .VRO files [fom DVD-RAM movies]. It's been awile since I used it, but I think it saves to avi or mpg format.
Oops! It saves in the vob format and didn't work on my "Stargate" dvd. It is working on a dvd I made though. If I remember right [this is getting scary] you can rename the extention to ".mpg".
Yup. I renamed the file with the ".mpg" extention and it played fine in JetAudio, Power DVD 5.? - not so good in windows media player [it streched it]. So you can extract vob to vob to mpg with homemade dvds or dvd-ram discs with this tool.
