That's a good start... It seems your parameters are expanded correctly,
your variables resolved correctly.

As I neither have .srt files, nor your specific AVI, is there any
material you could provide? There's no easy explanation for what's
happening on your side.

What else worries me ("script code review" ;->):

If I call the program according to usage(), I still get the usage info.
:-(  I think the -f info is wrong, but you're making things hard for
us...

You also don't check for the existance of the .srt file. And if "-s"
isn't given (e.g. I don't have .srt files), it silently ends.

Does the resulting target have the same framerate?

Apart from the fact that I'd reduce the audiorate a bit more, the
length of video and audio does differ, perhaps due to the segfault.
