no signal during watching tv channels

[maziv]

first of all thanks to your fast replay.
i have new problem with my qboxIII that is loosing signal during watching tv Channels without any reason in all dvb players app and i have to turn it off and on again from power to make it work again.
i used the latest driver and tested all olders on win7 x86 and x64 but still have problem.
i just want now this is my hardware or driver problem.
my pc config is
amd 640
ecs a780
4 gb ddr3
1 gb ati 5450 hdmi

Hi maziv

Is your signal is well enough?and would you mind tell us which sat and TP you are using?

Thanks
