[F8] Learn how to load video into flash files?

Does anyone know of any good tutorials to get videos on your flash website?

Im trying to either have them load onto my website....(which i cant get all of them to work) or just have them embedded right in my website?

I have all different file types that i've converted to .swf files so im working with swf files now...

I have attached a file that works...so why doesnt any of my other files work when i do the exact same thing?

Any suggestions or advice would be greatly appreciated!!
