Hello,<br><br>I have great problems with watching SD liveTV (via DVB-C) or playing<br>back recordings/DVDs with internal player.<br>The picture is jerky and lagging. I have been trying to switch mpeg<br>encoders, changed deinterlace settings, commercial flagging settings etc
<br>etc without success. The CPU load seems quite high ( 50-60%). However,<br>doing same thing with external player ( xine , mplayer, vlc ) everything<br>is smooth and fine. Do you have any ideas what would be wrong on my
<br>configuration ?<br><br>my mythbox is following:<br><br>cpu amd x2 be-2350 2.1GHz<br>memory 1G<br>500G sata hdd<br>Technotrend C-1500 for DVB-C<br>nvidia 7050PV<br>mythtv 0.20.2<br>mythdora 4<br><br>front and back on same machine
