are there any plans to implement ATIs/AMDs equivalent of VDPAU? Unfortunately I bought a mainboard with onboard AMD graphics short before I read about the (at that time "going to be implemented") VDPAU support.

Things look smooth but I still notice tiny juddering every now and then when playing 1080p content that has continous motion.
- Rachel, could you post your xorg.conf?
- Alan, did you say you had a Samsung A656?

Anyway... I'm considering taking a look the VDPAU and subtitles issues (that is that no overlay is present and thus ASS/SSA subtitles wont work)
I wonder if just someone can give me some pointers of where in the code to look around.
Cheers!

With VDPAU we obviously dont have access (via the CPU at least) to the video image, and so this composite operation wont work. What we aught to be doing is rendering the subtitles to an OpenGL texture, and having that composited via OpenGL directly over the VDPAU video - this would give some additional benefits even in software mode, losing a blit, and the ability to be able to scale and move the subtitles for example.
If you're serious about having a go speak to myself or elupus on IRC if you need more info.

If they're not VC-1, then make sure you have 512MB or more on your GPU - in the case of integrated cards, configure your BIOS to allocate this much RAM, if its an addon card with less than 512MB then you're likely just out of luck.
