Hi,
After installing RC2, I have had a problem with one of my receivers.
The Cinergy is working fine as usual.
On the HVR I am getting various channels with freezing or complete black screens. Recording fails.
These include:
Channel 4
ITV1
E4
Five
More 4

There are probably more.

BBC and many others are not effected.

I upgraded to the latest (not that recent) driver for the card, and this seemed to make a little difference, but I am still getting jumping TV (unwatchable) only on the HVR card.

Logs attached.

Just noticed loads of "Continuity error" - in TsWriter and TsReader logs.

Any Ideas?

Thanks,
Chris

EDIT:
Found it!! Seems on moving some stuff I disturbed an antena splitter and it stopped the card from getting some of the weaker channels.
Don't I feel stupid?!
Leaving the post for anyone else who may find it useful.
