Viewing TV Problem

[brit_sage]

Ok I have a bit off an odd problem that I can't seem to figure out.

Basically I went on holiday for a week so I shut down my server and thin clients. When I returned home I booted up the server then the clients only to discover I can no longer view or hear my TV (Sky Digital) via sage.

Following this to ensure it wasn't a client problem I installed sage on one of my computers only to result in no difference. From this result I assume the problem is server related. I'm using a PVR 500 where I linked my sky digital to it via scart to composite.

I can still change the TV channels via sage and my RedRat infrared controller, but just have a black screen and no audio.

does anyone have any idea of what could be wrong or how to fix it?

Thanks,

Rob
