No Video in LiveTV - PVR-350

[vbsm]

I'm using PVR-350. When I watch LiveTV, there is no picture/video. When I record and watch the recorded file using gbpvr, there is still no picture/video. When I watch the recorded file using MS Media Player, then you can see the video. I'm using the InterVideo non-css mpeg decoder.

Any Idea?

Thanks.
