What audio format for Mpeg1 on a DVD?

[LanceSteel]

I have some old Mpeg1 streams that I want to put on a dvd. I know that Mpeg1 at 352x240 is a supported dvd format but I have no idea about the supported audio format. The audio on the VCD is Mpeg1-II audio but the Dvd Demystified faq says that at least one audio stream needs to be in AC3 format (on a dvd.) Is that just for Mpeg2 video streams or for Mpeg1 video streams as well? I know my player will play them either way but I want to make these dvd's standard so that all players will be able to play them. I just want to make sure before I go and convert all the audio streams to AC3.

Thanks.

Dvd Demystified -- hmm dont know where they got that info because it is wrong -- you dont need 1 stream of ac3 .. you dont need any audio at all in fact but pcm or mpeg.audio or dts only will work also ..

for mpeg1 on a dvd -- exactly the same hold true ..

I believe that what "the book" means, is at least one track has to have a standard audio format, be it AC3, LPCM or MPA (MPG1-Layer II). It cannot be entirely DTS or SDDS or other specialized audio tracks.

But, hey, I'm probably just like the rest of you... I don't have access to the real DVD spec.

As for Lance's original question, there is no specific audio requirement for MPEG1 video, except that the maximum audio rate is 384kbps.

the whole specs are in 3 books - which yes , i do have a copy of .... but a lot of the specs are on-line also - this is a very good resource:
