Ok, so something strange is going on. About 10 days ago the V8 supercars channel disappered off my channel lists. Didn't think much of it, cause no racing until next week so figured TVNZ just stopped broadcasting it in the meantime. But 3 days ago TV1 disappeared also. If I try to change to that channel, Media centre simply skips to the next channel. When I scan for services,   TV1 and V8S don't exist, yet in my channel order listings it gives me TV1 (which is ticked) and a frequency. In another menu( can't remember which one), it tells me that those channels are not configured.
I have tried a system restore to 3 weeks ago, and it has made no difference. Have also redone the registry hack and that has made no difference.

And to boot, by internet at home has stopped (bloody Telecom!)

Can anyone help with some suggestions for me? Please?
