Hi Andrew,

My experinece is the same as Gergs, I can't get the board to work at all, I 
just get a stream 0x00 from /dev/video1, and can't make /dev/video0 work as 
v4l2 device at all (trying to use xawtv2.88).

Initially I was using 2.4.20 with the driver from linuxtv.org. I e-mailed 
Gerd Knorr at bytesex.org who suggested patching kernel to 2.4.22-pre and 
trying saa-2003813. I tried all this and the only difference it made was that 
I only get stream of 0x0 on /dev/video1 when there is a video source 
connected rather than all the time.

With both drivers the board seems to be recognised OK on start up and the 
driver loads OK, but just doesn't seem to work. By the way I'm using the 
version without the TV tuner

The board has exactly the features we are looking for so I bought 2;  it 
would be brilliant if it worked, but at the moment I think  I'm going to have 
to buy Haupage PVR 350 boards and just ignor the tuner etc.
