5.1 disc playing back 2-channel only

post #1 of 4
Thread Starter 
Not sure what's going on here...

Recently acquired several ac3 5.1 files from internet downloads (satellite broadcasts). No matter how I try to burn a disc, all I'm getting for playback is 2 channel stereo.

Initially, I tried simply burning the files in Toast. Although it reports the files as 5.1 Dolby Digital, burning as an audio CD or DVD, no luck. I then imported the files into DVD Studio Pro - again confirming they are ac3 5.1 - and burned a disc thru this app without success - only 2 channel.

What's curious is that both my dvd player and receiver display that the burned disc does contain 5.1 channels (front panel info). To make sure something in my setup wasn't amiss, I checked playback of my system with some commercial 5.1 audio-only DVD's and they play back fine.

Is it possible that a file can be tagged as ac3 5.1, but only contain audio on 2 of the channels? I realize dolby digital can be anything from multichannel to mono, but the number of channels contained in the file info would normally reflect this.

Any help would be appreciated = Thanks!

that's possible. why don't you extract the channels on your pc and take a look/listen?

I did check the source files and all 6 channels are present with recorded material.

Any thoughts why these files won't burn correctly?

you have to author a DVD-Video with video-ts folder to play in your standalone.
can be with DVDLab pro(30 days free) or with the free and cool...
GUI for dvdauthor: http://download.videohelp.com/gfd/index.html

look at "features" : - 'Audio only' titles (for music DVDs form mp2 or ac3 audio files)

cheers!
