Video look terrible over HDMI vs. VGA

Hi
I have a Radeon card and am outputting via HDMI to my Samsung HDTV. The quality of everything looks fine to me, even video games. The only issue I see is video. When I output from a 6 year old PC to the same TV via VGA video looks perfect, when I play the same video in the new modern PC the video looks grainy with artifacts. I have googled and see people having issues that affect the whole picture, in my case the issue is only with video playback.

The video is probably not HDTV quality...1080p (1,920 × 1,080 progressive scan)

Go to settings and reduce the resolution from 1080p (1,920 × 1,080 progressive scan)
down to  720p (1,280 × 720 progressive scan)
or 480p (720 × 480 progressive scan)

Pixelation could also indicate the video resolution is not matching the TV correctly and maybe you need just a couple of codecs.
Test your video and audio used in the video in Gspot codec analyser, even though it's an old tool I still use it to check any problems with playback. Open Gspot and drop your video on wait a tick and Gspot will produce a green line or red line  green line for codecs installed.
