sHiKoRa:
ATI 5450 is very good to HTPC, i have one too. If i am not wrong, the article about 5450 was written by testing on beta drivers, where some things was not working already. Now should be all fixed (it is working at last for me).
BTW, if you add FFDshow audio decoder in to MP postprocessing, try to remove it.
Thanks! That's exactly the one I had in mind: SAPPHIRE HD 5450 1GB DDR3 PCIE HDMI
I'll keep you posted on the progress.
Hoborg I promised to get back to you about my HD problem in MediaPortal. Since I became a dad it took me some time to have a look at it.
The issue was caused by the Nvidia driver, the Geforce 8200 itself wasn't the problem at all. Windows Update offered the Geforce Driver 197.45 (April 2010 driver). I installed this update and it solved the problem. HD content 720p and 1080p run now smooth in MediaPortal. Pretty simple solution, but that's often the case. The strange thing though is the fact that I tried different Geforce drivers before and it didn't solve it. FYI the Geforce drivers that came with the system were version 171.37.
Both SAF v4.00 stable and SAF v5.00 experimental (svn100512) work perfect!
BTW I did a small donation for your good work with SAF. Thanks Hoborg!
