Hi!
I finally got mythtv working (with a dvb card). Not an easy ride it was.
I'm still trying to smooth the setup of this, for instance, watching
live tv is slow. I don't know why - playing normal on-disc movies goes
smoothly. I wath tv via a dvb tuner, which works OK with pure mplayer
or xine. In mythtv however, both audio and video pauses every few
seconds and cpu usage is constantly 100 %:
top - 22:04:25 up 5:04, 2 users, load average: 4.54, 3.08, 1.84
Tasks: 100 total, 3 running, 96 sleeping, 1 stopped, 0 zombie
Cpu(s): 81.4%us, 11.8%sy, 0.7%ni, 0.0%id, 0.0%wa, 5.9%hi, 0.3%si, 0.0%st

As you can see, I also run my backend on this machine but it doesn't
use so much cpu time... I don't think this system is too slow for a
mythtv frontend?

P.S. Happy new year and to those who develop Mythtv: thank you! It's a
hard nut to crack configuration-wise, but what a powerhouse!
