Bug Description
This was not an issue prior to the Mythbuntu 10.10 upgrade
I did a fresh install of Mythbuntu 10.10 and now during mythtv-setup my DVB-C tuners hang the application during a channel scan. Prior to this I was on 10.04 with myth autobuilds 0.23.1 and it worked with no issues. On amd64 using 2 HVR-1250's
syslog reports this during the hangup
