I run a via SP13000 to watch DVB-T in the UK. But you have to use
accelerated playback to get a decent system running rather than relying on
the CPU. For this to work you will need the openchrome packages installed
(note Fedora 9 this should work out of the box):
For playback I then use the standard xine rpm from the livna repository,
then I use that to "play" a DVB channel using the following:
/usr/bin/xine -V xxmc dvb://BBC ONE
The key here is using -V xxmc to enable the hardware accelerated playback,
there are similar options to mplayer to achieve the same effect.
(note in reality I don't do anything on the command line, I just use
Freevo with the appropriate setup: http://freevo.sourceforge.net/)
