Media Temp

Question

Hey,

I was wondering, i've got a media player built into my application, and its running from a single url for example... www.filemanager.com/video.wmv and so when other people use this application i can upload another video with the same video tag "video.wmv" and the video will change for them automatically.

But when I use the application it automatically downloads the video to temp files (i assume) because when i upload a new video with the same tag it stays on the video i originally uploaded, is there anyway to disable it downloading it to temp? Or am I overcomplicating things? Any help would be great, thanks!
