Choppy video on a UMPC? Try disabling hardware acceleration

Yes, it seems counter-intuitive, but it just might help based on T-Bird's post over at the Origami Project. This is a simple registry change (although you should always be careful in the registry, even backing it up first) and essentially turns off the hardware acceleration on your UMPC if it has that feature. You'll be offloading the graphics work onto your CPU, so I wouldn't recommend any multi-tasking. Give it a try if your UMPC has struggled with video playback; you can always change the registry key back if it doesn't help or if it makes things worse! I'm happy enough with my video performance so I'm leaving things alone for now.

This has been very effective in sorting out video problems with Quicktime and HD video (trailers) on a few occasions for me. Though I've only disabled the acceleration in Quicktime, not the entire device.
