When I use MythTV's channel scan it gets to Channel 9 and says
"Locked" at the top of the screen and then hangs there after printing
"ATSC Channel 9 -- Timed out, no channels".

Here's the output from the terminal:

2011-02-06 21:55:14.472 Skipping channel fetch, you need to scan for
channels first.

Here's the output from dmesg:

The error output happens after the scanning of 189028615:8VSB. No
additional output is added during or after it locks up at the warning
message that is displayed.

Is there any additional information that I can provide to help debug this issue?

Thanks,
Dave
