Hi I have two MSI Mega Sky 5580 both of them show this behavior, when I try to use tzap sometimes like 8 of 10 times I get nothing. If I unplug and insert it again it works for sometime. Does anyone know what I could do about this. I have tried this patch, it solved some of the problems, but all of them. http://www.linuxtv.org/pipermail/linux-dvb/2007-February/015863.html Here are some output from dmesg during boot [ 40.775768] dvb-usb: found a 'MSI Mega Sky 55801 DVB-T USB2.0' in warm state.
