Sounds like you don't have enough system resources on the Windows side to run Coherence and the video... Try messing with your VRAM and RAM settings.
I had the RAM at Max.. I'll try again on Monday (when the stream continues) with the VRAM at Max. Thanks.
I tested it using Vista Ultimate and IE7 on a MacBook Pro 2.33 with 2 GB RAM (1100 RAM dedicated to Vista). I was required to download the latest FlashPlayer and did so. It was able to play the video and audio in Coherence Mode (I tested it in all modes) with no problem at all. I have WMP 11 installed.
