    QT not playing AAC auido in video files

    I had previously re-encoded a few mkv file to mov using QT and they had been working fine until a recent update. now QT will not play any AAC files at all. I have perian installed and everything used to work in QT naively. It's not the files as the work fine using vlc. But i need them to working QT you use front row.

    anyone else got this prob or know a fix?

    I assume the recent update is 10.6.3? If so… this is a widespread problem. See discussion below.
    Apple - Support - Discussions - since 10.6.3 - Quicktime: MPEG2 muxed ...

    Apple has released 10.6.3 v1.1 today to address bugs with 10.6.3. Perhaps that will help. If not, you may have to wait on an update to Perian.

    Please verify and include the exact model/year of your Mac and OS X version number (available from "About This Mac", then "More Info" on the Apple menu).
