At the prompt, you can use 'ivtvctl -a' to get a list of the card's
details and inputs - you'll need to specify the correct card too, so
use 'ivtvctl --help' to find out how.

The output above will show all inputs the card has that the driver can
access (usually more than the number of actual physical inputs). You
can then use 'ivtvctl -p x' where x is the number of the input to
switch to that input and test.

On my 350, I have 4 S-Video and 4 Composite inputs. On my 150 I have 2 of each.

You could also just cycle through the inputs in mythtv-setup and then
test each one to see which gives normal video.

HTH,
