inside of the [Youtube] tags you post what i bolded. that is the URL of the video from within the adress bar.

if it says "&feature=related," or anything else after that, ignore that. only that stream of numbers and letters is what matters.

when done right, this occurs:
[youtube]mBM2iGXrshU[/youtube]

embed and the embedding code is useless for SouthPerry uses. the tag itself will act as the embedder, all it needs is the video code to embed.

Code:

<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/_PeQ_bfAceA&hl=en_US&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/_PeQ_bfAceA&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>

In [YouTube] works too.
[YOUTUBE]<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/_PeQ_bfAceA&hl=en_US&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/_PeQ_bfAceA&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>[/YOUTUBE]
