ATI Radeon 4350 question with Windows 7 ..
JoeB:
Interesting, I'll try some other videos. I noticed that a lot of other things kind of "break" when DXVA is globally turned off.
- Windows Media Play 11 (SP1 default) works but if your system is up to date on security patches, it ships with WMP 12, and it complains that it can't find CODEC
- VLC Player fails playing. You need to go into options and set output to Windows GDI driver and it starts working correctly
At the end of the day, this is a dedicated PC inside a New Astro City arcade machine. As long as MAME and Hyperspin works, I'm done.
Does MAME use DXVA!?

That reminds me that I didn't check SFIV movies on fresh windows 7 install with HD5450 and HD4350.

DXVA can't be turn off globally. What you're turning off is DirectX hardware acceleration, which basically lets your system unusable (similar to using the default VGA driver).
DXVA stands for DirectX Video Acceleration, and only applies to video. It's a very problematic feauture, that's been prone to bugs even on unpatched drivers. If only it was possible to turn it off.
In modern PCs it's really not necessary and CPU usually does much better, the issue being that some software doesn't allow falling back to software rendering.
I know this is preaching in the wilderness, but there's a certain frontend that's getting in the way of many of you.
JoeB:
There's a simple reason for it. :)
Every MAME cab maker has to choose the lesser of 2 evils for their use case:
- A robust, feature full, flexible FE that was cleanly developed - but looks like it's from the early 90's (developers make poor graphic artists)
- A beautiful, easy to setup, eye candy FE that is poorly coded (artists make poor developers)
Going back to my original question:
- Does MAME use Direct X Video Acceleration?
