Installed MP yesterday on my pc, and i have to say i am very impressed with it. Very user friendly, well designed and very complete compared to MCE. I have everything working and am using MP for dvd, video, radio and DVB-C tv.

The only thing that really annoys me is the quality of the DVB-C. I am pretty sure it is due to the codec. I have a mobo with 690G AMD chipset and integrated X1250. Main problems are extreme ghosting (think interlacing is all wrong) and high cpu-usage, even with mpeg-2 signal. Also, there seems to be an overal bright tint in the picture and color depth is also pretty low. To make specs more clear: My cpu is an X2 3800+, 2GB or ram, 690G chipset, using regular MP codec for mpeg-2 decoding and cyberlink for h.264.

Important specs about the 690G chipset (why i choose the thing in the first place):

Motion Video Acceleration Features:
-Enhanced MPEG-2 hardware decode acceleration
-MPEG-4 decode support
-Hardware acceleration for WMV9 playback
-Supports top quality DVD and time-shifted SDTV/HDTV television playback with low CPU usage

TV Out:
-Integrated TV encoder from ATI's Xilleon products with on-chip -DAC with integrated AVIVO engine

My question: how do i know if the stream is hardware decoded and what codec should i use for mpeg-2 dvb-c decoding? If the decoding happens by hardware, why can't I select 'AMD mpeg-2 hardware decoding' or something like it in the list of video-codecs.

And more general: what codecs are most frequently used and give good result for both h.264 and mpeg-2 decoding, especially for tv signals.
