Dear All, I just hg'ed a new clone from http://linuxtv.org/hg/v4l-dvb this evening; cleaned out the old kernel modules; re compiled and installed and... It works! :-) I'm sure I tried exactly the same process a couple of times this week without success but I'm happy now. Thanks to whoever fixed it. bye ian Ian W Roberts wrote: > My Gigabyte U7000-RH was working until last night when I upgraded to a > new kernel build -I'm running Ubuntu 8.04 and (now) 2.6.22-15-generic. :-( > > Since then the device can't tune and I don't know how to troubleshoot > the problem. :-( > > I've tried re-making and and re-installing the the v4l-dvb.
