[mythtv-users] TV Screen Scrambled

Hi,

thanks for your help.

Finally, I've got it working, but the CPU load is above 80% and frames
are dropped every second or so (capture resolution 320x320).
It's a via m 10000 board (1GHz cle266) and a em28xx card (pvr 900). Any
hints to improve it? Is it possible to record the tv signal from another
box (mythtv frontend installed on that box) and watch it over ethernet
(wlan 11Mbit/s)? Is it possible to zap the channels quickly with such a
setting?

best regards

Dani
