I'm sure the correct driver is loaded, but I'm not sure that it's
mapped to /dev/video0. How do I verify this?
You're running the wrong tests. Accessing /dev/videoX directly is for hardware MPEG encoder cards; you'd need to jump through a bunch of hoops to access a framegrabber card in that manner. Just use "mplayer tv://[channel]" or xawtv to test a framegrabber card.
