Tried streaming through Orb, and found the video VERY choppy with both IE and TCPMP.
After some playing around, I found a simple fix:
Make sure you use IE rather than Opera!
Merely guessing here, but I think that Opera caches the stream on their servers, and this causes the lag.
Anyways, with TCPMP installed, and going through Pocket IE to my Orb box, I now get a great audio/video stream - even with DirectDraw
