Hi..

Sorry for my last mail, stupid keyboard...

It works... Thanks, now I can scan...

When doing
modprobe saa7134 card=70
I get this in dmesg
saa7130[1]: subsystem: 185b:c901, board: Compro Videomate DVB-T200
[card=71,autodetected]

Thanks to christoph4 at #linux-tv how saw that there is a diff in the eeprom

at http://www.linuxtv.org/pipermail/linux-dvb/2005-October/005423.html
there is a dmesg from DVB-T200 card

DVB-T200: saa7130[0]: i2c eeprom 60: 30 26 ff ff ff ff ff ff ff ff ff ff
ff ff ff ff
DVB-T200A: saa7130[1]: i2c eeprom 60: 30 ff ff ff ff ff ff ff ff ff ff ff
ff ff ff ff

This could be the thing to diff the cards from each other.
