Losing sound/picture when rewinding Live TV in Media Center

Dylan Tusler asked on

Using Windows 7 and Media Center, upgraded from Windows Vista.

All other parts of Media Center appear to be functioning as normal.

I can watch Live TV fine, but if I hit the chapter back button to skip back a few seconds, it works for the first couple of clicks, but then the video screen goes black (preview window and timeline still functions at the bottom of the screen.)

If I then wind forward to the current "live" area, picture returns but with no sound. Have to exit Live TV to get sound back.

The machine is only used for Media Center, but also has PowerDVD installed.

Back of the net...
