That's what's saying it's crashing in avidemux2.

This is saying that it got 0 Audio streams and 1 Video stream

And this confirms it, there's no mp2 file.

OK, I'm an idiot.  It crashed while writing the video.  Duh.  It never got to
the audio.  I should pay more attention. :)

I'm sorry.  I jumped to the wrong conclusion there (I'll blame the lack of
caffeine on a Monday).

I think someone in IRC had this issue and we tracked it down to something
funky in the version of cursed he had.  If you grab the latest nuvexport, I
have made it prefer the Xvfb server (virtual framebuffer) over cursed.  It's
still a glorious hack, but it will almost assuredly work better.  It seems
that cursed requires versions of libaries that aren't readily available to many
systems, although they are on FC1.  Xvfb is a "standard" XFree86 server, it
just uses memory as a framebuffer, no input devices, no display.

My apologies.  Please try with Xvfb and the newest version of nuvexport, see
if that works better.

Hmm.  Well as for where: the IRC channel is on the freenode.net IRC network,
and the channel is #mythtv-users.  Point your IRC client (like xchat or mirc)
at irc.freenode.net...

As for the timezone thing, I'm on EDT (UTC-0400 I think), but I'm on until like
2am most nights, so that would be firmly in your evenings.  We have people on
from Europe, Australia, all over.  So I wouldn't be too concerned about that.
Now not having time, that's something I can't help with :)
