Yes, i had the exact same problem (even ended up going to the XVID site on finding only the source ). Just get the latest divx codec pack.

Divx Ex codec

If that link doesnt work

http://www.divx.com/divx/?src=toptab...rom_/index.php

Theres the new codec on that site aswell (just below the table of the crappy player thing)

Then install it

Good Luck

PS: Great Episode BTW
