I can capture channel 1 under Windows using the VCR hack (haven't found 
any other channels I can get yet), but I don't get any output from 
test-mpeg2. Could you do me a favor and send the command line you use for 
test-mpeg2 and the output it's supposed to give?

I'd love to have my screen flooded with raw mpeg right now.. :)
