FrontRow's video play back is dependent on Quicktime. Which means FrontRow can't play your DIVX or AVI files. Out of the box Quicktime can only handle a handful of movie formats. Enter Perian - The Swiss-army knife of Quicktime® components. Download Pernian 0.5 and plug the many of the holes that QuickTime has in regards to playback of different media.

Specifically Perniam enables Quicktime to play FLV, 3XVID, DIVX, 3ivX, DivX, MS-MPEG4, Sorenson H.263, Truemotion VP6, XVID and more. Installation is quick and simple and then FrontRow will play all these movie types.

Of course WMV is not supported, but for that you can download Flip4Mac. For other strange 3rd Party Codecs check out QuickTime's Components. This includes On2, ZyGoVideo, iPIX, Zoomify, Streambox and more...
