That is a bummer. I looked into OCR and that is the best way, but from what I have read, it's not 100% and I don't have the time it takes to proof read. 
Right now I load up my computer with 5-6 DVDs and 100+ eps in vob format, hit my scripts and come back in a few days to a drive full of avi files. 

On the topic of OGMs. I have some OGMs that a friend gave me. They have optional subtitles and 2 audio tracks. I don't see a lot about encoding OGMs in 
mencoder? Can I do the same mecoder?  I can't have the subs split off into seperate files. I won't have mplayer with me at all times. I need to play this from a Win 
box if I have too. OGM is about as exotic as I want to get. 

Thank you
