Update your version of Windows Media Player http://www.microsoft.com/windows/windowsmedia/download/AllDownloads.aspx More info: MPG4: Microsoft MPEG-4 version 1 MP42: Microsoft MPEG-4 version 2 MP43: Microsoft MPEG-4 version 3 The story behind it... From codeccorner.com “It is widely accepted that Microsoft attempted to take control of the MPG4 standard by coming out with an avi version of the codec prior to the MPG consortium having voted a final standard. The code had to be completely reworked 3 times. Making matters worse, MS refused to rename the files, and since they were not backwardly compatible even more distress was created." Furthermore, Microsoft locked their codec so it could no longer be used to encode AVIs, but would only encode with Microsoft’s own ASF container. Then out of the woodwork people made cracks to re-enable AVI encoding (DivX 3 being the most famous; AngelPotion was another one, but a poor one). The cracks were just the Microsoft MPEG-4 version 3 codec with new names and AVI support. MPG4, MP42, and MP43 can be found in both AVI and Windows Media containers. They should be included in any standard installation of Windows 2000 and XP. If for some reason they were accidentally lost or deleted, any of the links at the top of the page should work. In Windows 98 (first edition), they will be installed if the proper boxes have been checked during installation. (If not, go to control panel, add/remove programs, windows setup, multimedia, and check the box netshow player - you may be asked to insert your windows 98 cd) If the links at the very top fail get the old Windows Media Tools, which were used to create asf files with MPG4, MP42, and MP43. Type wmtools.exe into your favorite search engine (the Microsoft site doesn’t carry it anymore). For those interested in encoding in MP43 (it’s still a fine codec) in AVI (perhaps because you are concerned about the legal status of DivX 3) you can find it at http://www.undercut.org/msmpeg4

Should they encounter MPG4 or MP42 in an avi container, they can get QuickTime plugins here MPG4: http://homepage.mac.com/hmason/mac-ms-mpeg4v1 MP42: http://homepage.mac.com/hmason/mac-ms-mpeg4v2 — NOT DONE — Needed: MP43 (for AVI) for Mac OS

Just a guest Guest Both of these alternatives to QuickTime will play asf/wmv files with M4S2, MP42, MP43, WMV1/7, WMV2/8 video compression on Mac OS X. MPlayer OS X - has built-in decompression for other formats such as Indeo Video 3 - FREE http://mplayerhq.hu/homepage/design7/dload.html http://mplayerosx.sourceforge.net/ < — — NOTE: Version 2 *requires* Tiger for proper functionality. VLC (VideoLAN Client) - FREE http://www.videolan.org/vlc/download-macosx.html
