Lo there,
As requested the backtrace of a common segv when watching pre-recording
video. I assume that glitches are being introduced into the nuv file
from my dvb-t nova-t cards (Mt digital signal quality isn't so hot) and
mythtv croaks. I've never had a problem with watching the same files
using mplayer or xine but they are not as hot as mythtv.
Regards
Simon

I remember when legal used to mean lawful, now it means some
kind of loophole.
