So busy lately but yes I did manage to remain married, be a father, and a grad student - I'm bragging only because I'm sure I went out of mind going through one corrupt build of a brand new system.....
Sounds like we're using similar hardware. Due to all the problems I had with dxva on Vista x64 and x86 with the AGP 2600xt, I stuck with Windows XP on this new build. I'll have to turn off dxva in the cyberlink options for h/x264 and see what happens, it's hard to tell with the quad core at 3gHz compared to the AMD64 at 3Ghz but I suspect dxva is working on the correctly encoded material. AMD64 was at 15% cpu, now at 1% with said material with dxva turned on.
It's a monster thread, but there is the 2600xt owners thread at AVS forums which will tell you a lot about dxva, if you're eyes don't start to bleed and obscure you're vision.
I still need to fully assimilate the direct show wiki...just so busy, but I'm down with working out all the details of dxva of various formats.
Actuallu, I just posted a possible bug because I can't get .mvk playback or import in the newest version of MC...go figure. It was working the other day, and I'm pretty sure I didn't make any serious system changes. I just ran 4-thread Prime95 for 32 hours at 3gHz and also ran memtest (the one Matt suggested on these forums) concurrently in windows.
BUT, I have been seeing a grey screen lockup which is bizzarre, and I'm pretty sure I saw this on my last board with the same card. Gray screen with vertical gray/black stripes, I think it is the gpu crashing, maybe I have a bad card. It happens every now and thing, when the gpu isn't doing anything serious, in fact during stress testing the system the gpu never made it over 47 celsius. Granted I need to loop 3dmark or something....but something is fishy. Since I was so busy I used the same XP install from a 790FX board.....I booted into Windows on the DFI P35 Ut and removed all the Gigabyte drivers, chipset, etc. and crossed fingers. Probably the root of my issues, maybe not, I was just too busy to re-install; didn't even intend on doing it, I just booted in by accident because I never hit any key to install windows....I read you can do this OS upgrade if you mess with the ACPI/standard PC stuff (remove/add) but that's prior to the upgrade. Runs smooth, snappy, and primes, but hopefully a bad card or the miniport driver which was two versions old and upgraded yesterday - I also had a bad HD hooked up externally via firewire.
anyway.......
