Philips 642 can't decode AC-3 Mpegs?

[oldfart13]

Just noticed that my brand new 642 can't apparently decode AC-3 audio from Mpeg-2 ISOs which are produced from Womble Video Wizard. It also won't play straight VROs burned onto a DVD- or + RW. Odd that I would have to have Mpeg-2 audio or author into DVD for them to play. Anyone else have this problem?

Nope butI can play AC3 audio from avi files through my receiver but I can't play DTS audio from avi files. The DVD player just passes the audio to my receiver though which decodes the sound.

One annoying I found out was that when I try to play dual audio MPEG-1 ISOs I got from some VCDs of mine it can't seperate the audio channels so I get two different languages at once but it can seperate them fine when I play the VCDs.

Bummer that. Guess I'll have to look around for another player since I have 46 rewriteables with Mpeg-2 and AC-3 audio that this can't play...

At first I thought this player was incompatible with the audio in my raw MPG, VRO, or VOBs. Then I found the trick!

Have you tried the audio channel selection button (bottom right corner) on the remote control during playback?

I found my MPGs and VROs with AC-3 audio would play the audio after I selected the correct audio channel 80 or C0 for tivo extracted files. At first I was lost on what to do other then fully author out everything, but after I pressed the audio button on the remote and found the trick I was convinced this player could handle any file thrown at it. This feature should really be noted in the manual. After I stopped on each channel for a few seconds A 0-7, C 0-7, 8 0-7, I found my audio and video were both there. My heart started beatting again after that!

Good luck!

Well its known that for example the ac3enc engine out of the present ffmpeg core isnt able to produce 100% AC3 specs compilant AC3 streams.
Why do I menion that? Cause it "could" be that the programmers of such softwarer "could" have used that core of ffmpeg! As we all know that commercial program authors do often have a "look" into the open source scene

Just a guess ...

Many thanks 4packsadvd. The setting for AC-3 audio playback is C80. Works great! Now I don't have to take the player back after all and the DVD rewriteables can be used in the 642.

I just found out today about all these audio selections settings when playing MPEG-2 files on ISO DVD.

Yes, the setting for MPEG-2 file with AC-3 audio is 80.

And the setting for MPEG-2 file with MPEG audio is C0.

But I couldn't get MPEG audio from VOB file from DVD disk recorded on LiteOn 5001.

I too stumbled across the "C0" audio fix. Is there a way to make it default to that setting when playing "mpeg" files?
