Not quite, "VDR" is a very nice PVR project for dvb cards, it can output
to DXR3 (also via FFMPEG), which works very well.

I must try Freevo, being a big python fan myself. I like the Freevo
philosophy. Freevo is just a lightweight gui and is completely dependant
on other applications such as mplayer for media playback. I wont comment
on "slowness" except to say... no.. I wont say anything :) In any case,
hardware requirements should not differ between mythtv -> freevo,
certainly not because of python :)

I use mythtv obviously, so dont take the above as 'anti-myth'. Myth
seems to be more mature atm, and will always be more integrated (at the
expense of greater complexity). I'm gonna keep one eye on Freevo tho :)

Once I got the module parameters right, I never had a problem with my
dxr3. TV-out (svideo) quality was much much superior to NVIDIA
tv-out(svideo). Still useless for mythtv mind you.
