I'd like to apologise, as I'm not too experienced with Linux and
that's actually my first experience with DVB-S. So I might be giving
some stupid answers or maybe asking some stupid questions...
But I'll try to answer your questions, one by one. So:
1. I have my antenna positioned to Hotbird, I assume the DVB stream is
MPEG2 PAL (I'm almost sure of that).
2. I'm not specifically trying to run XvMC, as I don't know what it
is. Most of the settings are at their default values...
3. I have Matrox G400 graphics card with "unofficial MGA driver" from
4. I'm currently using KDE.
5. With my current setup, I'm able to play video files (DivX/XviD,
MPEG2 and so on) in Myth. It runs smoothly and with only 20-30% CPU
load. As I'm not yet going to watch HD channels, I expect SD MPEG2
stream from my DVB-S card should not be a problem.
6. On the same machine I can watch Sat-TV just by typing
'mplayer dvb://<channel name>'. The video is fine and I don't see any
I'm not sure what else I should mention... Please ask questions if
something is not clear, I'll try to answer.
