I'm running on a fedora 9 box, so at least that tells you its not OS related. I posted this problem on the list a while back and didn't get any response. Here is my post out of the archives: http://linuxtv.org/pipermail/linux-dvb/2008-July/027367.html http://linuxtv.org/pipermail/linux-dvb/2008-August/027670.html It makes me feel a little bit better that its not just me. _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
