Stoxpoker Videos won't play on my desktop

[Bobo Fett]

I'm having a very odd problem playing Stoxpoker members' videos. I can play all of them fine from my laptop. I can play SOME of them fine on my desktop.

I am attempting to play them by clicking the "download" link on the website. When they work properly, they start buffering in Windows Media Player, then start playing once the buffering is done. For one that doesn't work - it shows "buffering”, and when it gets to 100%, it starts playing – sound only, and for only about half a second. Then the buffering starts again, plays when it reaches 100% for half a second, and so on, and so on, until the download is about 90% done. Then it plays straight through, but again, audio only…black screen. Audio sounds perfect, but there is NO video.

I am running Windows XP Pro Version 2002 SP2, all updates installed; and Windows Media Player 11.

Anyone have any suggestions?
