I have just bought my first ever PocketPC, an IPAQ 4150 with the 400mhz
xscale CPU. I have been very impressed with it's video playback using
PocketTV and WMP. With PockeTV it can play back 320x240 30fps mpegs from my
SDRAM card without dropping a frame in fullscreen mode. Does not run quite
as smooth in windowed mode, presumably because the scaling down takes quite
a bit of extra CPU time.
WMP also runs just as well with either local or streaming video. 300kbit
streaming web video plays just as smooth as on my desktop.

Overall I am very impressed with it's multimedia performance as you can tell
Wasn't sure what to expect since this is my first PPC, but it's
certainly a very capable CPU packed in there.

I've ipaq h1940 (266 mhz), no problem playing mpeg and wmv videos, very
smooth play (>15 fps, can be better too if the mpeg or wmv are encoded with
higher fps) and sound.

On some review bench mark tests are much faster than 400 mhz models.
