Windows 7: Poor/Pixelated Video Issues.

Well if it happens after format then its weird. After driver install (win 7 dedicated of course), run newest dx redistributable package. I dont know if the newest is already included in win 7. But may be already.
Next thing that come to my mind is wrong video renderer used. Run MPC Home Cinema and in options/output make sure evr/evr cp is checked (oh 12eason suggested that). Do u see pixelation with WMP too?

Yep indeed, it`s weird. And yes, the quality is still poor in WMP and I have tried playing with Directx/Rendering in output etc, then again it kills the aero. Seems like I am suffering the same as this people over here on this thread Poor video quality - Windows 7 Forums. No solutions yet, It`s really a weird situation..

Another hint.... If u use ffdshow for decoding videos, go to video options>>output and make sure that YV12 colorspace is UNchecked. That can lead to pixelation too. Thats somehow limit on Windows 7 and evr. Dont know why others decoders (including WMP) may force that colorspace while evr cant accept it.. Could be also 64bit system problem or graphic drivers.
Well... so if u run 64 bit system, u may try 64 bit ffdshow along with 64 bit MPC HC. Wonder if evr fail in both x86 and x64 decoding chain.

MPC HC - DVD


WMP - DVD


MPC HC - Filter


If WMP and MPC shows the same amount of quality how can it be codec related? Oh and pixelation only appears when I run MKV files, mostly when forwarding.

Ok lets things clear now. When you are using vista/seven default renderer should be evr: http://img41.imageshack.us/img41/3121/schowek1d.jpg
Im on xp now but look on renderer description/name.
I dint see pixelation on your videos. So u watch just poor encoded avi.s right(?). Somebody had the same problem on that forum and he claimed he's gonna download better quality encodes.. Or when u watch videos on high resolution display u may have bad scaling. And if u put dvd screenshots then better change to cyberlink pdvd mpeg2 decoder (free in k-lite) not internal one in mpchc.
"mkv files" means NOTHING. Any container has inside video format that is decoded by dedicated dshow filter (i guess it may be h.264 decoder).

Hey man, thanks for busting your ass aiding me really appreciate it. I agree with the poor encoded thing, atleast for the avi files. All though they did scale just fine on XP, not the best quality but ok. Anyways, when I switch to EVR on MPC I seem to get a pretty decent quality, but it`s like the screen takes over the entire explorer, the only option I get is rewind/forwarding and I cant seem to escape the windows besides heading to taskmanager and execute the MPC. Thanks for beeing patience with me, I am not that experienced with video codecs/formats.
