Windows 7: DVB-T - Background not smooth

Hello there.




I watch TV (DVB-T) through my MCE Windows 7 Ultimate x64.

Well, when the subject moves there's no problem, but when it's the background or the entire frame to move, it's absolutely not smooth, sometimes awful.

This is the configuration of my Asrock Vision 3D 252B:
Processor Intel Sandy Bridge Core i5-2520M (2 x 3.00 GHz (3.20 GHz Turbo), 32nm, 3MB L2, 35W)
Chipset Intel Cougar Point HM65
Memory 2 x 4 GB DDR3-1333
Graphics NVIDIA GT 540M (1 GB VRAM) 650 MHz / 1300 MHz / 900 MHz
Intel HD Graphics 3000 650 MHz / 1.3 GHz (Turbo)

I have no idea which graphics card is in use when I watch TV, I found no way to check.

Trying to solve the problem I installed 1st K-Lite Full codec pack, then also K-Lite Full x64 codec pack, nothing to do.

I also have no idea which codec is used, I tried to manage FFDshow video decoder but it seems to have no effect.
Also enabling or disabling hardware acceleration for MPEG2 seems to have no effect.

The TV card is a MSI DIGIVOX Micro HD DVB-T USB 2.0, seems to have no problems on other computers.

Computer is connected to TV via HDMI.


No idea what else to do.


Can anybody help me?


Thanks and best regards
