I know I could do an experiment but I don't have the necessary files on hand.

When I do AVI-> MPG w/TMPGenc and I have a properly named SRT or
SUB/IDX pair in the same folder, DirectVobSub kicks in automatically and
burns permanent subtitles into the MPG.

Does/could whatever AVI to MPG program S2D uses do the same thing ?

I'm obviously not looking for selectable subs, just would prefer to use S2D for the whole job - it's so much easier to do it all in 1 shot

TIA, QE
