What GPU and VPU tests have you been running? Jon Nettleton, I, and others have been running XBMC with VPU acceleration, Chromium with EGL-based drawing enabled + with my VPU patches (which I will release here in a few days) running HTML5 Canvas and WebGL tests, and gstreamer-imx with the EGL-based video sink that uses the Vivante direct textures. Using the jellyfish test files: http://jell.yfish.us/ , XBMC has shown to play h264 bitrates up to 100 Mbps (higher ones exhibit framedrops).
