I installed Mythbuntu over the weekend. I have a Hauppauge HVR 2250 tv turner card that I followed the instructions on linuxtv to install. I believe that it is working correctly, but when I go to set up Mythtv and scan for channels everything comes back as "timed out - no signal."

Any ideas on how to fix this issue? Let me know if you need any more information to help me problem solve.

Thank you for your help,
