[mythtv-users] numexport failing -- not sure where to look for answers

I'm very new to MythTV.

I've got MythTV (v .21 from repository packages) both front and
backend up and running on an old PC running kbuntu 9.04 with an old
Happauge card using the bt787 driver (planning to buy a more modern
tuner once I get things up and running)

I'm able to record shows, watch tv, etc but I'm trying to export a
recorded show to something I can view on a PC.   I've installed
nuvexport and am trying to export to xvid.

Currently, I'm using mencoder.   The conversion seems to start off
well enough.  It seems to get to the end and the process just dies.
I've included both the actual run output and the --debug output below.

Another question aside from trying to find why things fail, why does
the progress indicator not seem to understand how many frames it is
trying to convert?

"processed:  105161 of 1784 frames (5894.67%),"

Err what?

Please help!
