How much CPU is required is hard to tell. It largely depends on the 
video size (h/w in pixels), the decoding type (MPEG2/4), the used 
bitrate of the streaming video and if hw overlays off the video card can 
be used.

I was mainly referring to PDA (like Intel StrongArm1100 or XScale) as 
used in iPaq's. The 206Mhz StrongArm1100 types are not so good in doing 
large sized video's and Mpeg4. The 400Mhz will do better at this.

If the device has hardware that does the decoding, then the CPU does not 
have to be that fast.

Only from telnet in vls.
