Re: VDPAU + Composite - slow on GTX470 (some videos)
Still exists with latest pre-release, but it seems to me that situation got better: I'm experience "freezes" only at start (after window is created till first frame is dislapyed) and when rewinding (not always, but usual it takes up to minute to rewind file).
Everything is gone when switching back to -vc ffh264 or turning off composite manager (kwin).
I've even updated kde to 4.5.74 (4.6-alpha) - no changes.
