Q: Front Row plays audio but not video of MP4 H264 AAC files

SL 10.6.6

Here's the problem:

Take an MP4 movie file encoded with H264 and AAC thats plays with no problems in QT, iTunes, Front Row

Open this file in QT7Pro, add a mask using a GIF file then export as MP4 using video and audio pass through to avoid re-encoding

The new video file plays OK in QT and iTunes but only plays the audio track in Front Row - the video is just presented as a blank screen

This happens to every file i've tried it with.


I've tried trashing all front row caches/prefs/app support folders, installing/uninstalling/re-installing perian. i've tried changing the file extension to .mov .m4v .3gp - still the same problem the file plays perfectly except in Front Row

All the posts I can find on this topic seem to refer to subtitles causing a problem - these files have no subtitle track

Any suggestions?
