video file coding

[jack]

I used thoggen to convert a video-ts file into theora (.ogg), but I
would like to convert this to a .iso file and burn it to a dvd.
Searching for info on this, I found some forum articles that suggested
mencoder for this, but I haven't been able to get mencoder to cooperate.
Is there someone here familiar with mencoder that can assist ?  Or would
transcoder & xmlauthor also do the job ?
