thank you for reading my post and here is my problem:
My Windows Media Centre ramdomly freezes while changing channels or accessing guide during tv watching.
I have tried everything I could from reinstalling the W7 64bit and updating all drivers and I all works fine with DVB-S single tunner but once i use Dual DVB-T tunners the problem starts.
this HTPC has core 2 3ghz and corsair 2GB 800mhz ram and HD 3870 512mb video card running tv with hdmi cable and two physical DVB-T tunners.
When WMC freezes I can't access windows desktop to close apps as mouse keyboard and remote do not respond and that surprises me because W7 is better in that sense.
thank you guys
