Hi, I built a purpose built media centre using Windows 7. I havent sorted EPG yet until I get other things working.   For some reason it keeps losing TV3 C4 Prime. All the ones on that frequency or what you call it. This is DVB-T.  TV1 TV2 etc all good even though sometimes get bad pixelation on 7.   I rescan and it finds channels then day later says no tv signal.   I have a DVB-T TV and the channels are fine.  I installed avermedia media center and again all channels work perfect no problem. Avermedia wont play my mkv files and wont turn computer on and off like media center remote will.

My setup is
Gigabyte GA-880GM-UD2h motherboard
2gB ram
250gb hard drive with windows 7  32bit
1.5 Terabyte hard drive for recordings and files
Avermedia Trinity Tuner card
400watt power supply in Antec nsk2480 case.

I have tried a ati 5450 hd graphics card with same results even pixelation
I have tried Nvidia 8400 graphics card and Nvidia 210 all with same results, so have stayed with inbuilt graphics which is ATI 4250 HD

I can live with pixelation as it is only on 7 and not all the time.  Has anyone any suggestions for the losing channels.

Thanks
