Hermann and Peter,

I guess it was me with the Vivanco card in May/June last year. I took a time 
out from the mailing list due to time constraints, but am back and willing to 
help you sorting out the open issues, as far as my limited competences allow 
for it.

The current status with my Vivanco 21057 card (4e42:3306) is:

- DVB-T works with the patches you suggested last year
- Analog not (but did not bother anyway)
- FM: did not try
- Remote: dto. (I'm sitting in front of the computer anyway)

Funny thing: since Kernel 2.6.22, firmware upload does not work any longer. I 
have to boot XP before and do a warm reboot, then DVB-T under Linux works.

Best regards
Werner
