YouTube embed and 3.6

[hinch]

Has anyone got a bb code replacement for youtube working with vb3.6 I tried to set one up today only I just get a white square instead of the video embedding properly.

example:

[youtube]http://www.youtube.com/watch?v=7tEkKhMVoS4[/youtube]

to be replaced by

<object width="425" height="350"><param name="movie" value="{param}"></param><embed src="{param}" type="application/x-shockwave-flash" width="425" height="350"></embed></object>

and this is the string from the generated html
now to me this looks correct however it simply refuses to display the actual player
