Vista - Windows Media Player

running Vista Ultimate
We have a security camera that takes a short video when motion activated. The file is then emailed to the tech guys. I cannot view the video. It opens Windows Media player and then just sits there with a blank screen. I can use XP and the file plays just fine, just not on my Ultimate computer.

May want to try downloading a codec pack

Well I did download a codec player and I can view the videos now, but that still does not explain why they will not work in Media Player.

When you try to open them in media player, what error message do you get?

No error message, just sits there and does nothing

When you play the file, in the bottom left hand corner, do you see any status updates or in the now playing area do you see anything, a filename with a red exclamation mark or triangle?

Also, which codec pack are you using and what format is the video?

Video is a .asf

.asf is a weblink to another file, like on a media server for instance. If the file has been moved from the location, then media player will do nothing. Open the asf file properties (right click, properties) and see where the link leads. if its a web address, put it into a web browser and see what comes up.

Not a web link, its a file, size is 205KB

205KB is pretty small for a video
