Video HW output with ATI

[Jack Knowlton]

Hi all.
I have a Ubuntu HTPC running 10.04_amd64.
Until some time ago I had a Nvidia 8400GS card and was able to use the
vdpau output in mplayer (with packages from "cutting edge" repo).
Now I have switched to an ATI Raden HD 4350 with the fglrx driver.

Since I have changed the GPU, 1080p MKVs don't run smoothly anymore and
sometimes even 720p playback has a few hiccups now and then.
Is there something equivalent to vdpau for an ATI card?
I don't care for gaming, desktop effects and so forth, but I expect movies
to playback without trouble.
Thank you.
