Quoting an entry buried in the help forum:
The v4 [and v5] player uses a completely different API, details here: http://code.longtailvideo.com/trac/wiki/FlashAPI
Sadly, that URL doesn't work. Now I expect Open Source software to have either completely useless, or just plain absent documentation, but we (and a great many others) have paid for this player - so its not acceptable.
