My QuickTime 7.0 Pro for Mac OS X can't seem to play .AVI files. What do I need to add to it, &?

Hmm...I don't have much experiance in MacOSs or Quicktime but I believe that you need an codec for it. Try looking around on the Quicktime website. That should give you more answers.

If you are attempting to play AVI files, they require codecs.\n\nCodecs are special filters that manage how a video file is played back. There are many of these codecs, and which one you should use is generally dependent on a given file.\n\nYou should try getting the latest Divx codec. That will play back most AVI files.\n\nhttp://www.divx.com\n\nAlso, you should look into the G-Spot appliance. It is a program that will tell you what codec is used; you can then search for the appropriate codec.\n\nhttp://www.headbands.com/gspot/

possibilites is that you don't have that spesific codec\nusually avi (divx) codec is not preinstalled in you computer try installing divx player.\nanother issue is the .ac3, .ogg (vobris) files have the same issue like the .avi files try installing matroska pack

Probably because the movie is loading.\nDo you have the latest version of Quicktime?

If you don't have DIVX player installed you should get that. It's free. Almost all non quicktime/real player movies will either play in divx or Windows Media Player. The install will also have the divx codec for media player.

The people that say Macs are shite will never be right.\n\nDownload VLC media player to play your videos.\nhttp://www.videolan.org/vlc/

most of the videos on yahoo have been formated for viewing on the PC. Your best bet is to go to microsofts site and get windows media player for mac. It should give you the program and plugin. For me, it still only works about half the time...

Try playing the file(s) in vlc (http://www.videolan.org).  This will play almost anything.\n\nYou say you have all the updated codecs, but it still sounds like you're missing something.  Try getting the Gordian Knot codec pack at http://www.free-codecs.com/download/Gordian_Knot_Codec_Pack.htm\n\nIf it still doesn't play, then maybe there's a problem with the files themselves (did you download these files?).  Good luck :)

Well, you cant actually “view” audio files but downloading and installing quicktime is a sure fire way to take care of this issue. It will play audio and video in almost any format.

Try any of the following:\n\nWrong CodDecs:\n\nThere are lots of movie formats. The most popular ones are .avi, .mov. wmv, .asf and .mpg. \n\n.avi = DivX --> www.divx.com\n.mov=QuickTime format --> www.apple.com/quicktime/\n.wmv, .asf and mpg are native to Windows Media Player.\n\nJust download the right codecs from the sites I specified. :D\n\nWrong Players:\n\nUse the right players for the format you're trying to play. Do note that if you have the CoDecs installed then Windows Media Player would do.\n\nReally, really, really old display cards:\n\nThis is a bit far out, but if you're using really old display cards, like the 4bit ones like the old SiS or S3 cards. You ran a chance of the movies not playing. Especially if you're running them in 800 x 600 resolution. Your hardware can't accomodate that load. If this is the case, please change your display card.\n\nReally, really, really old monitors:\n\nSame case with the old display cards, old monitors won't do it either. Change your monitors.\n\nDrivers for your display card:\n\nYou might be using drivers supplied by your OS. Try downloading the correct driver for your display card be it 98, XP, Linux whatever. :D Hope this helps.

try getting a free copy of VLC media player. it will play just about anything there is, or look for the codecs for avi and the type of mpeg you are trying to play on line, download them and put them in the codec foldae in windows media player

Search for some software on the net which will either play it directly or convert it to some which you can play with your existing software.\nEG :\n*.mov,*.3gp = Quick time player .\n\nOr you can post the file extension here so that more specific help can be provided
