How to make videos stream?

[JerkyChew]

I know this is kind of a Linux or Apache-specific question, but I need to enable this for just one domain in Plesk, so I thought this would be a good place to ask.

We're hosting two video files, one MPG and one MOV. We'd like them to stream when the user clicks on the link - Right now the browser tries to download the whole file before it plays the file.

IIRC, there are some settings that can be changed in Apache to force the video to stream before playing? Is this true, or am I way off? Any help is appreciated.

Thanks.
