What that refers to is the codec that was used to compress the goal video originally.
Most of the vids use the divx 5.1.1 codec to compress. If you download the divx bundle you should be able to view all the goals; I can & that is the only codec bundle I have.
If you already have a divx bundle installed on your pc, un-install that first, as it may be an older codec program. Also run the "search all files & folders" option for "divx" in the folder title & delete all the files/folders, just to be sure.
Then install this
Hope that helps!
