I can only see the [youtube] tag in Dan's post, I can't see the first. I think disabling [video] tags is a good idea.
So over the last month I've been trying to find a solution to this. Disabling the [video] tag is easier said than done, and so far vB has been unsupportive of this. I need to upgrade to the latest vB, but the hack that is being used for the wiki would not be compatible, so I've not done this yet. I'm considering moving the wiki back to its own fresh site (not integrated with vB) so I don't have to deal with the incompatibility issues in the future.
On the plus side, I now have an android so I can play with solving this issue. For the time being, we'll have to deal with it, but I will add it to the list for when I upgrade.
