Looks like this nice fix is broken by the recently QT 7.4.5 update. Any help appreciated

It doesn’t seem to work, Perian installed and configured as above, plist changed, settings changed in Audio MIDI setup. But what did you guys choose next to format:
2 channel 16 bit
2 channel 20 bit
2 channel 24 bit
encoded digital
I tried them all, but non worked. Only 2 channel give me output but offcourse in stereo. Anyway others tips? Did I forget something

thank you very much i needed this so much. for those of you who don’t know how to edit plist, you can download plist edit pro for free(shareware)follow the instructions and everything will work great provided the avi/mkv etc is surround supported.thank you once again

Works fine on Leopard, although I head to search a bit to find and then edit the pList file - I had to install XCode first to install the pList editor. One question however - Front Row also plays VIDEO_TS folders, but these are only played in PCM stereo, and not passed on digitally to my receiver - while Apple DVD player or VLC do! I guess this has to do because Front Row launches the DVD player as a helper app and as Front Row already uses the digital transmission, the DVD player can’t.

Great tutorial! Those running Leopard: just search the web for com.cod3r.a52codec.plist - then copy it to the mentioned folder.

Has anyone been able to get DTS passthrough to work?

Thanks for the info!
But now I have a bigger problem:
If I change the format to 48000.0 Hz, webvideos from youtube etc. won’t play anymore, because they only work under 44100.0 Hz.
Any solutions anyone????

Thanks for the tutorial. Unfortunately I can’t get it to work. I’m using Leopard and the only thing I see different is that I’m using Perian 1.1 and I’m unsure if this is the cause.

I get some sound, but it’s very choppy, or just pure rapid stuttering. My receiver does not detect any type of Dolby Digital signal.

When I play the same video file through VLC, I’m able to get 5.1 Dolby Digital sound with no issues.

I would prefer to get Quicktime working so I can use FrontRow. I’ll try downgrading to Perian 1.0, but other than that any suggestions? Thanks.

Great Site!

I just wish I could get mine to work. I have tried all of the steps and still I cannot get QT to play the AC3 encoded movies.

I can play them fine from VLC, I can also rip DVD’s and access them via Front Row - again both play full 5.1 channels.

However, as soon as I try to play them through QT - silence.

Can you possibly offer any ideas?

Thanks in advance.

This is great! I’ve been trying to figure this out for a long time!
The only problem I get, is that I don’t always want to use my digital output. I only use It for watching movies in the room next door.
So when I unplug my reciever, quicktime tries to pass the ac3 channel trough the built-in speakers which off course doesn’t sound very nice.
