@ wannabee
from the url in the address bar, like this:
[YOUTUBE]JxOqq_CThf8&feature=player_detailpage[/YOUTUBE]
Paste everything after the first = sign in the address.
The Youtube tags are in advanced post settings. Cut and paste into that.
Hope this makes sense. Note: using the embed button at Youtube is usually futile. (It can be used only to see if the clip has embedding turned off, and that is about all).
