This assumes your soundcard is perfectly clocked to the incoming DVB stream? I'd assume that eventually if the soundcard is a bit faster than the DVB stream, you'd get an xrun. Maybe it's an idea to add xrun counts as well. Another thing which would be good to get statistics about: the average number of "hurryup"s after a channel change. -- Torgeir Veimo [EMAIL PROTECTED] _______________________________________________ Softdevice-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/softdevice-devel
