Installed Vista to discard issues with the card and can only get 3
channels, probably an antenna issue, but one of them has pretty
acceptable quality. I get the same results with WinTV and choosing
PAL-N and Argentina for the frequency table. With try-all and PAL-N on
mythtv 0.21 this is what I get for the same channel (local Channel 9)
138 ---> No audio

Same channel with WinTV:

Is there any way to take the frequency table from Vista Media Center or WinTV?
