Checked radio with DMCradio (v4l1) and tv with mplayer both work perfectly.
Thanks Thierry! Great work!

Yeah Thierry has done a great job... I did notice that the master volume resets itself when I was using kdetv and changing channels. I'm going to try mplayer like you did and see if I can replicate the behaviour.
1. v4l2 video worked perfectly but the volume resets during TV channel changes. Used kdetv.
2. v4l2 radio worked perfectly, no problems whatsoever. Used Thierry patched gqradio for v4l2.
3. v4l1 video, could not get it working.. Most likely a Dwaine problem.
4. v4l1 radio with v4l1 gqradio did not work. Most likely a Dwaine problem.
5. Belkin device patches worked fine, did not impact any other NT1004 and NT1003 devices.
6. I see the less memory usage too.... Mauro will be happy.
The only thing left to do is the audio-over-usb and the vbi stuff. The audio-over-usb was working ok..
It's amazing to see when everyone helps out and contributes, what can happen.
