[mythtv-users] laggy LiveTV and lag with internal player

[Andres]

Hello,

I have great problems with watching SD liveTV (via DVB-C) or playing
back recordings/DVDs with internal player.
The picture is jerky and lagging. I have been trying to switch mpeg
encoders, changed deinterlace settings, commercial flagging settings etc
etc without success. The CPU load seems quite high ( 50-60%). However,
doing same thing with external player ( xine , mplayer, vlc ) everything
is smooth and fine. Do you have any ideas what would be wrong on my
configuration ?

my mythbox is following:

cpu amd x2 be-2350 2.1GHz
memory 1G
500G sata hdd
Technotrend C-1500 for DVB-C
nvidia 7050PV
mythtv 0.20.2
mythdora 4

front and back on same machine


regards,
andres
