[linux-dvb] Re: Simens MXB not working

[johannes@bjbecker.de]

Hello Michael,

Your tip was right. After using your procedure it is loading the drivers. But I can't use any 
programs. I have added the ourput of dmesg after loading the drivers and also the result 
of czap (same result with scan). The devices seems not be available. They do exist in 
/dev/dvb, but nothing inside. Also /dev/video.

What is wrong?

Johannes

Well, not every saa7146 based card is a DVB card. The MXB is an *analog* 
  TV card, so you should use the "mxb.o" driver from the "analog-2.4" 
directory of the "dvb-kernel" CVS driver.

For futher informations have a look at my MXB project page at
http://www.gdv.uni-hannover.de/~hunold1/linux/saa7146/mxb.html

There are compilation instructions plus additional background 
informations. It's possible to use the driver with the "DVB" 
video4linux-1 driver, just in case you have an saa7146 based DVB card, too.
