Hey.
have just started to use mediaportal. and i got some picture quality issues.

i have taken some snapshots so you guys can see the prob. (when have bin redirectet by the link Right click and "Save as" to see the pic correct)

i have upload some FULL-Size no scaled pic's so you can see what iam talking about.

The first is an in-movie pic. of avatar. 720p this shot was taken in mediaportal

The on is a in-movie pic. of avatar. 720p. shot was taken in BS.player

both shots was taken att the same time in the movie. the shot in meidaportal i much more blured and noise. any idea what might is wrong ?

I you take a look att this pic. (Tv real time in HD) you can see it got the same problem. Noise alle over the place. its an digital feed. and i does not look this way when iam watchin tv (the normal way, non-mediacenter)

Hi Jones,

its all about the codec. Go to MP Config and tell us, which codec for h264 is set.
Try the CoreAVC and PowerDVD10 codec. if you can and then compare the results with your current pic quality.

You can address your problem in the SAF thread, I think those guys can help you much more.

Jones9000:

I do not known much about DS player, but i think the problem is DXVA decoder VS software decoder.
You didnt post your HW info, so i think you are using some modern GPU.
SAF using FFDShow DXVA decoder to decode h.264, so if you have DXVA GPU, GPU do the decoding instead of CPU. Maybe you have badly set your GPU drivers - for example, there is a lot of video postprocessing setting on ATI catalyst.

Maybe DS player doesnot have DXVA decoder, so it decode h.264 using CPU only. Thanks to this, your GPU settings doesnot have any effect on picture quality.

EDIT:
You can confirm this by change MePo video renderer between EVR and VMR9.
If you are on Win7 set it to VMR9, if on XP, set EVR - this will disable h.264 DXVA.
Just make sure you setup it correctly after test.

Just tried the powerdvd 10 codec and that makes it work... thank you both for your repley.
