[mythtv-users] mythfrontend CPU usage while playing MPEG2

[Thomas Börkel]

HI!

When I play a recording or live TV (capturing with PVR-250, 7000/8000 
KBit), mythfrontend uses 25-30% CPU time and sometimes it's a bit jerky.

When I play a DivX (1500 KBit) with MythVideo, mplayer uses 1% CPU time.

When I play an MPEG2 (3000 MBit) with MythVideo, mplayer uses 1.5% CPU time.

Why is that? OK, the examples have less bitrate and lower resolution, 
but still a Celeron 2.6 GHz should play MPEG2 full resolution high 
bitrate with lower CPU usage.

Any ideas? Is there any optimization possible in mythfrontend?
