Hi, folks
Here is a patch that should add support for the Medion MD8800. Since i don't
have such a card, i need your help for debugging.
The following should work
- auto detection
- analog tv via tuner
- analog CVBS and s-video
- DVB-T
The patch applies to my personal repository or the official repository of
april, 1st at linuxtv.org
Please test and report.
A question: should the board support FM-radio?
Best regards
Hartmut
