Youtube video in flash webpage, only letterbox player appears, no Widescreen?

Hi,

Im using this

VideoMc.loadMovie(“http://www.youtube.com/v/WHO7-y84ibs”);

The [COLOR=blue][COLOR=blue !important][FONT=verdana][COLOR=blue !important][FONT=verdana]video [/FONT][/COLOR][COLOR=blue !important][FONT=verdana]loads[/FONT][/COLOR][/FONT][/COLOR][/COLOR] perfectly etc. But the video always comes in with a 4:3 ratio with ugly black bars on the top and bottom. Even though the original video is in widescreen 16:9 ratio and even youtube has made its default ratio widescreen which means the base black video box is always in widescreen now on youtube. Even the 4:3 videos appear centered on that with black bars on the left and right. Thats ok with me and logical.

But why when loaded into a flash website it comes in with only a square ratio.

Any ideas how i can change this please ?

Thanks
