Synopsis:
-----------------------------------------------------------------
Previously i used another motherboard with onboard graphics with Media portal and i had 2 different issues with VMR9: one was 'normal' tearing in both DVD and TV playback, and one was a banding/blocked tearing/vibration in TV only, where every other blocks of lines seemed to be offset, similar to interlace ghosting except in most thicker bands/blocks. Before, i used overlay instead which removed the problem, but due to OSD problems with overlay, i have now changed my motherboard and im using a better graphics card. I have no 'normal' tearing now in VMR9, *BUT* i still have this banded tearing/vibration when watching TV(DVD works), timeshifted or not. It occurs mostly when there is alot of motion, but it is *not* the normal interlacing effect.
I am using a VGA->SCART adapter, and i have tried turning tiling on/off to no avail. I considered whether or not the TV might be at fall, but i have watched many DVD's using the same codecs as for TV(also tried others on TV) and i have never seen this problem. DVD playback is perfect, so i find it hard to believe that its the TV thats causing this.
On the other hand, when i log in via VNC, the images i see does not show this behavior, they are just showing normal interlacing effects.
Im pretty desperate, as i just used a lot of money to get VMR9 working properly and now i have this weird problem. Any help is appreciated, even if its just some comforting words
I have tried illustrating the problem below:
'real' image:
------****------
------****------
------****------

etc.
interlacing artifact:
------****------
----****--------

etc.
What im seeing:

EDIT:
I managed to re-create the problem in Zoom player when using the VMR9 renderer, and playing back an MPEG-2 file captured from another TV program. To my surprise, when i pause the playback the artifact is clearly visible. I took a screenshot http://www.itu.dk/people/petert/_/banding.PNG.
The image is from Gremlins 2, showing a rotating door gone weird. If you look at the vertical lines, you will see that they are broken up as i indicated above.
I guess this is not directly a Media Portal problem, but maybe just a general VMR problem. Even so, i would greatly appreciate if anyone could help me out.
From experimenting with Zoom player, it seems the problem disappears when the video is display 1:1 and becomes terrible if the image is scaled in any way, but even so it happens all the time in Media Portal.
EDIT 2:
I now tried playing some Divx or Xvid movie i had, and it plays perfectly, no artifacts. However, if i play one of the files captured from WinTV 2000 using the PVR-150MCE also using my video, i get the problem!
This is driving me crazy ;(
