.mov (AVC+AAC) files can't be played with sound

[watcher]

Hello!

The above-mentioned video files can be played only without any sound. These videos are HD (1920x1080) in Apple QuickTime .mov container. All the codecs are installed proposed by codec manager. By the way there is a newer version (1.13.138.14) of Haali splitter. Can it be the error?
The OS is Windows 7 Ultimate 64-bit.

Of course other media players can play these files with sound! Frankly speaking it is ridiculous! "Try one of the best multimedia players in the world." Is it a joke?

Thanks

Can you send us a sample of such .mov file?
