MPG files play fine on computer, no audio on DVD player

[kenimpzoom]

I burned several .mpg files onto a DVD using Burnaware Free. They play great on the computer from the DVD. But they wont play any audio on my Samsung DVD player. Video looks great, just no audio.

Any Ideas?

Thanks, Ken

the audio should be dolby digital. It's probably mpeg-2 audio. higher end authoring applications will encode the audio to dd for you but otherwis you have to seperate the audio stream from the video and compress it to dd. There are some freeware utilities that will do the dd compression for you but they escape me right now..someone will come along to assist .

I used Any Video Converter to make the file. It lists ac3 as the audio codec. I have other choices of mp2 or aac for the codec.

Any idea if those will work?

Sure ... but do you really want to "re-encode" the video when simple demuxing and re-encode audio would be best

ac3 audio is not inside the DVD specifications. You have to select mp2 to be sure the disc will play on a standalone DVD player.

http://dvdauthor.sourceforge.net/ states the following:

"AC3 and raw PCM are the only two audio formats guaranteed to be supported by every DVD player.

North American DVD players may or may not support mpeg 1 layer 2 audio"

Mods, et. al.: Chime in on this - I believe the info that I have is correct.

Otherwise, why have I spent all the time converting audio to AC3? Even when I author with TDA I select AC3 output.

Most DVD players don't support ac3 for file playback,only DVD playback. It's true that mp2 is not officially supported by the NTSC DVD spec,it is supported by the PAL spec. Since the vast majority of DVD players are sold world wide most will support mp2 audio. Why not convert your mpg files to DVD.

OK, first of all we need to know what format we are dealing with here. Saying that you made a DVD means nothing. Some people say that when they burn data discs. Put the DVD in a PC and look at the contents. Do you see directories named AUDIO_TS and VIDEO_TS? Does the VIDEO_TS directory have a bunch of VOB, IFO and BUP files in it? If not, you don't have a DVD and that may be part of the problem.

WRONG! AC3 is valid on all DVDs and all DVD players MUST support it - no exceptions.

jman - thanks for the update. I knew there was a reason that I've paid extra for software to work with AC3 audio all these years.
