Autotune determins wrong PID for AC3

for MTV-Central MediaPortal determins PID 33 for AC3 this is wrong and leads to issues:

1. with Skystar2 you get "no signal"
2. with floppydtv you get video but no audio

PID 33 is not a AC3 stream its a User Private Stream.

ATSC uses 0x81 (User Private Stream) for AC3. BUT DVB uses PES.

so PID 33 is not a AC3 Stream of MTV-Central (it doenst have one)

If you set AC3 PID to 0, MTV-Central is working again.
