Hi folks. New to Mac Forums and Macs in general. Just bought a brand new Intel iMac last night in fact. Anyway, my problem is playing AVI videos with Quicktime. Originally, I couldn't get the sound to work at all. I installed a few codecs and tried MPEG Streamclip. Streamclip originally worked and I was able to play the videos with sound, but no sound from Quicktime. However, after a reboot, both Streamclip and Quicktime play sound, but it's all sped up and distorted. Here's what Quicktime reports my format as: Generic MPEG-4, 640 x 480, Millions MPEG-1 Layer 2, Stereo, 44.100 kHz I have the following components in Library/Quicktime: AppleIntermediateCodec AppleMPEG2Codec DivX Decoder DivX Encoder Perian XVIDDelegateMacOSX.sit FFusion XviD_Codec 1.0 alpha Save as AVI If you have any suggestions, let me know. Like I said, I'm brand new to Macs and I'm sure I messed something up here.
