dvbdream & windows 7 problem, need help please!

[bay]

Hi all,
i have asus 7131h dvb-terrestrial and windows 7 build 7260.
I have a strange problem with dvbdream only under win7 and not on Vista Sp2:
the image quality is very poor. I see a lot of pixels.
I tried all codecs: dscaler, cyberlink, nvidia, and all video renderers.
I think it depends by the video renderer. It's possible to use enhanced video renderer??
Actually i use progdvb and all works well, but i want change to dvbdream.
Please help me...i'm going crazy!
I want to use dvbdream!!!!

What codecs may i have?

i don't think it's a codec problem, but the problem is the renderer inside dvbdream.
The same thing happens with altdvb and with past version of progdvb. Now i use progdvb because is updated frequently and the image in very clear.
