I was using driver 188.8.131.52 for a few months before the problem happened.
I will try using DVBDream.
How can I tell in Windows Media Centre which tuner is being used?
I do not know how to select another decoder?
The chipset is HD4350 which has hardware mpeg2 and mpeg4 decoder.
I will update the Catalyst driver to the most recent version and let you know the version.
For your first issue:
>About 6 weeks ago the following started to happen.
Is this means that before that ,all is ok ?before that which driver version you are using?
>When a scheduled recording is taking place we cannot change channel, screen goes blank on the other channel and says "service not available".
Also if a scheduled recording is about to start on another channel, Media Centre changes to that channel.
When is problem happen,Would you mind using another Soft to test the other Tuner which is not used by MCE,such as DVBDream.
For your second issue:
This maybe the decoder problem,would you mind using another decoder and have a test again.
