embeding flash flv video problem

I have been trying to add a "flash flv" video file using object tag..but I didnt get the solution,the follwing are the conditions when using the flash video..

1.the page along with the flash video should be xhtml valid.

2.the flash video should work in multiple browsers

I spent hours for this,but I didnt get the answers...so ppl please help me find the solution

 

Did you upload it onto your own server? If so, you will have the correct address, right?
For example : http://www.yoursite.com/videos/video_01.flv.

Visit - Cold Link. Add the video there, get the embed code. Use that.

Hope this helps.
Cheers

It says server trouble in coldlink..ya,actually thats a youtube video...so I placed the url they had given,the issue is without embed tag,it is working in all browsers except mozilla version 3....but it works in the previous versions of mozilla...
