Hi Dam,
first of all thanks for the reply. You asked me for some further information:
a)Freezing program: The device I use is shown as 713x BDA DVBT Tuner. I have no idea what it is called, it was pre-installed. I am not sure but what I found out in the device manager was a device called Creatix SAA7131, Hybrid Capture Device. I have no idea where to find the codecs and where to save them to, just in case you expected this
b)Time Shift: Thanks: this is an sufficient explanation
c)Closed receiver service: No, I can't start it again or better said: it can be started just to realize it is shut down again, due to the Data Execution Prevention, DEP policy. There are some more people looking for help in German forums with exactly the same problems with Media Center and AVSTV Box. And as far as they and I found out it seems to be no problem of codecs. But this is only as far as I see
MS offered some help (see the links to the knowledge base articles) but this does not help on my system as these hotfixes are already included in SP1. Probably it is a problem of codecs, so I hope to find the newest ones (but see under a))
I already thought of repairing the system using a restore point without knowing whether this is a good help....
To be honest: I'm a bit desperate because everything was fine until I installed AVS. :-/
Hope to get some help (as I like the AVS products and would like to use them) TIA
Gerd
