I update to Mythbuntu 12, I have a PVR-150. When I do a scan for channels during setup, no channels are found. I have analog channel 3 input.

I tried increasing the setup scan time out to the max, but still not channels found

I tried different distros of mythtv, mythdora, LinHES....all have this same problem.

If I have the same pc and input setup and install an older version of Mythbuntu...channel 3 is found no problem.

Is this a known problem? How can I get this to work? Thanks
