Hi, I've been debugging more and things are getting really weird.
When I "cat /dev/video0 > /tmp/testmpg" I get nothing, unless I press a key while the cat is busy. Then all of a sudden the testmpg file contains data. There seems to be a slight delay between pressing the key and the start of the recording, because when I press a key and immeadiatly afterwards ctrl+c the file is still empty. Another thing I tried was playing with the debug level using ivtvctl and came to more weird conclusions. When debugging is set to a higher level (e.g. 2 works) I can make the "cat" work without pressing a key, BUT I have to display the kernel logs before I get data in my testmpg file. So when "tail -f /var/log/messages" is running in another terminal, the testmpg file gets data, otherwise not. The data that comes out of video0 seems to have a really low frame rate, but I'm still investigating this.
