First of all, let me thanks everybody who helped me to troubleshoot my
problems. I'm now running MythTV using my G400-TV and the Marvel
external external Rainbow Runner tv tuner without almost any problem.
And the TV-Out of the external Rainbow Runner module is working also
perfectly ;-)

The only problem now is the really poor resolution when watch or
recording TV. I had a Hauppauge WinTV before and it was using CPU
but the quality of the resolution was much better. Is there anything I can
do to have much better resolution ? I went to the Configuration->TV Options
->Recording and put the resolution to 720x480 for "Default" and "Live 
TV" and
it does not seems to change anything.

Does anyone have a clue ?

Thanks again for this wonderful software, !Vive MythTV" ! ;-)
