how do I add a button for vids etc

[Femphysiques]

Thanks...but I already have youtube and google...what I'd like to have is a button that operates similar to their code. In other words....the ability to embed a vid from any url..not just youtube or google....example [vid]http://www.xyz.com/samplevid.mpg[/vid]. I know this code won't really work as typed above..just using it as an example.....also I guess there is a problem about constraining the vid to a certain window size....similar to the youtube or google vids....so I'm wondering if any code guru's here can help me out on this one...because I have no clue how to do it......Also...I'm not sure it's even possible as the youtube movies are really flash movies and not mpgs....anyway....thanks in advance...

Is there anyone who can help on this one?..thanks....
