You can try 9.10 too, there was some DXVA update acording to changelog.
BTW, what CPU do you have?
CCC 9.1 I tried as well, as it came with the last chipset-update (accidantly). - same effect. Went back to 9.5 - same.
My CPU is:
AMD DualCore, 4850e 2,5GHz
i mean 9.10 not old 9.1.
...i have bad felling you hit limitation of your chipset.
If you have chance to try, test ATI 4550 - i have this card (fanless) and it runs without any issue on my HTPC WinXP based.
What's the difference between "9.10" and "old 9.1"?
Had the thought about the limitation already but should work smoothly according to
Smooth HD Playback With A Sempron 3200+ - Review Tom's Hardware : AMD's New 780G Chipset Has Powerful GPU
?
ATI 4550:
Well, that would be
+35 EUR
+25 Watt
What is the difference between "Sapphire Radeon HD 4550 HyperMemory low profile" and without HyperMemory?
