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): http://wiki.openchrome.org/tikiwiki/tiki-index.php?page=Collection+of+contributed+binary+packages 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/) >From my experience you MUST get the accelerated playback via XvMC working to stand a chance of playing mpeg content on a small via system. And you won't get anything working for h.264 high-def content. Your 100% cpu usage indicates that the lack of acceleration support is the problem. _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
