    iMac G5 won't play avi videos
    My iMac G5 won't play downloaded videos in avi format. When I try to play it it just shows a white screen with garbled audio. The file works fine on my brothers imac when he plays the file with quicktime, but mine is just white screen. Anybody know what the problem is?

    You need the right codecs for the avi video. Chances are it will be using a popular codec such as the DivX codec. You can download that at .

    Dont worry, there's nothing wrong with your iMac, it's simply that you havent put on the software.

    If after installing the divx codec and you get no sound when playing avi files in Quicktime, trying installing an audio codec as well (instructions provided in link).

    under a rug
    13" MBP 2.53 DC2, 09 Mini 2.0 DC2, 07 Mini 2.16 DC2, MB 2.0 DC2, iBook G3 900MHz, G4 Sawtooth 1.6Ghz
    or you can just go and get Perian and install that and that will allow you to play just about everything you can find in quicktime as well as all the audio.

    highly recommend

    with perian you will be able to play all of this with quicktime:

    AVI, FLV, and MKV file formats
    MS-MPEG4 v1 & v2, DivX, 3ivX, H.264, FLV1, FSV1, VP6, H263I, VP3, HuffYUV, FFVHuff, MPEG1 & MPEG2 Video, Fraps, Windows Media Audio v1 & v2, Flash ADPCM, Xiph Vorbis (in Matroska), MPEG Layer II Audio
    AVI support for: AAC, AC3 Audio, H.264, MPEG4, and VBR MP3
    Subtitle support for SSA and SRT

    You need to download the right codec for the file type - got to Apple downloads and get them most are free. But the easiest thing to do is get VLC player which will play just about anything.

    Another vote for VLC. It's free and played absolutely every kind of file I have. It's the best download I've got.
