Thanks for your reply, but I don't quite grasp what you have done. I need to 
make an AVI file (xvid/divx or whatever) from my original recorded 
VTS_01_1.VOB. And, to be more specific, one that can also be played on the 
LG RH7500. I'm at a loss with all the parameters :-(
I'm not a video guru, just a modest computer user...
Could you suggest an ffmpeg command line to accomplish this?
Is info from an AVI file (from internet made by someone else, which does 
play fine) of any help?
