Does QuickTime Player Not Like AAC (AC3) Audio?

I converted a DVD to MPEG2 using WinX DVD Ripper and there was no audio during playback in QT Player but no problem in Streamclip.

Suspecting it may be the AAC (AC3) audio, I converted it again but using mp2 audio.

This time it was fine.

So am I correct in thinking that QT Player won't play AAC (AC3) or is there some way of getting it to do it?

24" 2.8 GHz (Penryn) 4GB RAM iMac, Mac OS X (10.6.2), Iomega 1TB USB 2.0 HD + LaCie Quadra 500GB HD

It's gotta be something else, Ian. AAC is the default format for the iPhone, iPod, iPad, iTunes, etc. Practically everything in my iTunes library is AAC and it plays fine in the QT Player. Just checked it again - AAC's play in both QT X and QT 7.

AC3 is another matter (it's Dolby) and I don't think QT can play AC3 audio. There are AC3 codecs for QuickTime you can find on the net (but I haven't used them).

There are some on the internet, but I have not been able to get any of them to work. I just want this thing to WORK. There must be some simple add on or something. Why would there be no codec for a basic video/audio format?

I'm sorry, but what are you talking about. MPEG-2 files from a DVD are muxed. The audio is embedded in the video. It has nothing to do with the codec used.

Have you purchased the MPEG-2 Component from Apple?
