Problem writing to video device

[stefan@pettersson.tc]

I am trying to make a video recorder for my Siemens Fujitsu DVB card, using 
driver version 0.05. The problem occurs when I try to playback a previous 
recorded file and write from my memory buffer to the videodevice. The problem is 
that the process hangs after a couple of seconds (sometimes longer and sometimes 
shorter time.) After a while it hangs almost immediately and then I get no 
picture at all. After having reinstalled the driver modules I can run it for a 
couple of seconds again and so on. I have traced the problem and it hangs in the 
write(buffer => device) command. But I am stuck with the problem - I cannot 
figure out why it happens.

I am running Red Hat linux and a kernel version 2.2.14. I am also using the 
i2c-core.c file from the last driver release as described in the news file.

To test my hardware and the driver, I tried to run the gVideo application. It 
works pretty well, also the playback function, but sometimes it also fails. Then 
I get a black screen which remains even if I quit the program and start it over 
again. The problem remains until I have reinstalled the driver modules into the 
kernel and/or rebooted the computer. (And sometimes the computer hang when I try 
to remove/install the modules)

After a long time of debugging I am starting to getting pretty mad. Therefore I 
would like to ask if there is someone knowing anything about this problem - if I 
am doing anything completly wrong or if there is some problem with the driver 
itself. I would appreciate if someone knowing anything about the problem would 
like to please tell me somethings about it...  

Thanks in advance

Regards, 
Stefan
