Well I'd suggest the latest driver from the main repository: http://linuxtv.org/hg/v4l-dvb and see if the problem still persists. If dmesg tells you right now that you're using a cx18 driver less than version 1.0.4, things should get better with the latest driver. Instructions are here: http://www.ivtvdriver.org/index.php/Cx18 but last I heard, Ubuntu does some distribution specific things that may make compiling the latest v4l-dvb repo harder than it has to be. Sorry, I won't be able to help with that if that's the case. > Any idea of when you have time to look at this issue? It sounds like > you are very busy.
