I have a backend/frontend machine that is a P3 1GHz w/ 256mb ram and
it's been running good for me. I have 3 capture cards (between 3
backends) - WinTV, Compro Videomate TV Gold+ and a PVR-350. I am able
to watch live TV and playback all of the recordings without any
problems. The TV-Out card in this box is an nvidia 5200 based card.
My recording profiles are as follows:
Compro and WinTV both do RTjpeg -
size:480x480 quality: 250 mp3 sound (one card does 48khz other does 32khz)
PVR-350 does mpeg2:
size: 720x480 quality: 4500-6000 mpeg2 decoder for sound @ 384kbs
Nvidia xorg snippet:
Section "Device"
#VideoRam 4096
# Insert Clocks lines here if appropriate
Identifier "VESA Framebuffer"
Driver "nvidia"
Option "TVOutFormat" "COMPOSITE"
Option "ConnectedMonitor" "TV"
EndSection
Hopefully you can find your 'magic' settings before having to give up
:) I found my stuttering problems went away after I changed my
recording profiles. Try various settings in those and see how it
goes.
Another thing I did was to uncheck 'Enable realtime priority threads'
if mythfrontend was not running as root. (utilities/setup > setup >
tv settings > playback)
