I bought a Kworld PlusTV HD Hybrid Stick 330 tv tuner to use with my tx2510us. All I want to use it for is basic analog cable. The problem is that the video is very choppy. I have tried using windows media player and arc soft total media 3, but both have the same results. I have tried changing settings in arcsoft with no luck. The odd thing is that the cpu usage doesnt go up too much at all, even with high performance mode. any help would be appreciated.
