Combine BB Codes & Custom BB Codes

[ximcix]

I added a custom BB Code to embed video clips in posts, but some members can't seem to differenciate between "Reply" & "Quote" so they end up quoting the a post with a video embeded. As as result thatre are severral instances of the same video clip throught the thread. Even though I set the "Autostart" parameter to "false," it still stars automatically in FireFox. I figured that since vBulletin does not currently support nested quotes (& I hope is stays this way) I usually wrap [quote] tags around my [VIDEO] to idiot-proof my post from chronic quoters, but my forum's members don't. So I would like to make quote tags a part of my custom BB Code, but instead of the desired results, the [Quote] tags are simply outputed as text & not parsed.

My current code:

<embed src="http://www.website.com/movie.wmv"
EnableContextMenu="false"
autostart="false"
controls="true"
loop="false"
TYPE="video/x-ms-wmv">
</embed>

I would like to be able to use:

[QUOTE]
<embed src="http://www.website.com/movie.wmv"
EnableContextMenu="false"
autostart="false"
controls="true"
loop="false"
TYPE="video/x-ms-wmv">
</embed>
[/QUOTE]

... and have vB parse the quote tags as well.

Is there any way to acomplish this?
