Divx 6.8.5 not compatible with Windows 7
I Ripped DVD with Magic DVD Ripper or #1 DVD Ripper with external codec which is Divx 6.8.5, but there is not work in Windows 7. Moreover, there is work with Windows Vista!
DivX 7 for Windows is a free download that provides everything you need to enjoy high-quality digital videos on your computer, including HD H.264 (.mkv) videos with AAC audio and videos created using all previous versions of DivX technology. You can also play your DivX files (.divx, .avi) on millions of DivX Certified® devices today. Look for DivX Plus HD Certified devices later this year that will support playback of all DivX and DivX Plus files, as well as .mkv (H.264/AAC) videos from the Internet.


winoutdoor,
DivX Codec 6.8.5 is currently shipped in 32-bit versions. You can use this on Windows 7, but if you have installed the 64-bit version of Windows 7 be careful to start the 32-bit version of Windows Media Player. Both versions are present by default on Windows 7 64-bit.
Hope that helps!
