I'm trying to add permanent subtitles to vcd which I converted from avi. For this purpose I use TMPGEnc 2.5 and Direct VobSub 2.23 and this is what happens : in the field where I select .sub or .ssa subtitle (in vobsub) after I aply changes it always takes me back to .avi file (and not .sub or .ssa). When I preview the film subtitles are appearing and disappearing from minute to minute trough the whole movie.
Can someone tell me what is the problem or recomend me some other software?

Thanx in advance and sorry for my bad english !
