Steve,
I changed the VIDEO_INPUT option to DEV1 and I'm able to record video now and bsdktr_tvtune does not crash anymore. The only thing is when I record and then play the output there is no sound. The mplayer output says AO: [oss] 44100Hz 2ch Signed 16-bit (Little-Endian) but now sounds comes out.
Also I changed the output size from 160x128 to 640x480 and the output has many dropped frames. Is that cuased by the slowness of the CPU or HD to save all the frames? Or do I have to play around with some more settings to get it to work right?
If you're trying to capture 640x480 raw frames to your disk there's a good chance you're overrunning your IO subsystem. Usually I have to compress the data a bit before I try to write it to disk to get the full stream.
If you were in windowsland I'd suggest Huff_YUV, but you're going to have to go for Motion JPEG at a high quality setting or something.
