I tried the above suggestion with night's CVS (Aug 28 11:00 p.m. EDT) 
and it seems to work.  Skipping and scanning work correctly.

I didn't  check the elapse time before transcoding but the hour long 
show claims to be 21:28 long.  Its seems that something in the cvs 
update may have changed the way elapse time is calculated.  Its late 
and I don't have time to time the length of this show but 21:28 seems 
like the amount of time that would be cut out of an hour long show due 
to commercials.  So this calculation may be reversed.  Was this 
something that was in the verbose patch Issac committed earlier tonight?

The audio seems lower pitched after transcoding too.  I'm using native 
alsa support.  Should I start a new thread for that one?  Or, is it 
normal?  The file was transcoded with uncompressed audio @ 48000 
sampling rate.

Thanks for the quick work around, Geoff.  Will CVS overwrite the 
changes to NuppleVideoPlayer.cpp with the next update to it?

Have a relaxing Labor Day.
