Hello, I have system with MB model intel 915GAVL and pentium4 dual processor 1.5 GB DDR RAM and use Pinnacle internal PCTV stereo card for TV viewing. My system uses both win XP SP3 and windows 7 ultimate. I have recently added nvidia 9400GT 1GB PCI Express graphic card. The XP version renders the TV video clearly when i use the PCTV software and I have also used the patch to solve the audio problem for it. But my recently installed windows 7 unable to render the graphics of the TV. The sound is clear but with no visual. I'm using the PCTV Stereo latest drivers which supports XP. Please help. I really love windows 7 but I think i have to switch back to XP just because the TV is not working.
