Solution: DivX Web player error 403 after update to 1.4.
Edit: STAGE6 IS SHUT DOWN. This means that all videos supposed to be streaming from stage6.com are not working. This is not a player error, and unfortunately cannot be fixed in this manner. However the divx-player is used on other sites as well, and is not affected by the stage6 shutdown. More here
If you use DivX Web player you might have noticed that some embedded files from other pages don’t work anymore after the 1.4 upgrade.
I don’t know why this is, but the solution is to download version 1.3 of the Divx Web Player and not update it.
Download Divx Web Player 1.3 HERE (oldversion.com)
…oh and it would be cool if you left me a comment if this works for you so I know,
Thanx, and happy holidays 
Edit: [Not really currently appropriate greeting but I'm sure there is a holiday somewhere right now...]
