GWater, Ok sure seems that the DQBUF ioctl isn;t getting called so no video stream.
However it also seems you are using the gspca_sn9c20x module with an older version of the whole v4l subsystem. Please make sure to unload all v4l related module and use the ones that are compiled when you compile the hg v4l-dvb repository. The following modules should be the main v4l modules you need to make sure to use the latest version of gspca_sn9c20x gspca_main videodev v4l1-compat Don't know if this will actually fix things but you probably shouldn't be mixing module versions just to be safe. If things stil don't work after doing that post the new debugging log and i'll take another look.
