Just tested a youtube embed copied right from their site and it works tested in IE and Firefox.

I don’t use the default bbpress template however, I wonder if that is affecting it somehow.

Are you using the updated v0.02 that I posted, not v0.01 ?

If it still doesn’t work, can you view source on the outputed page and copy just the part with that one post with full html here (between code tags obviously) so I can see what it is doing?
