mpeg layer 2 for dvd

[tonemgub]

According to this sites dvd specifications page (vcdhelp.com/dvd) I am not supposed to use mpeg1-layer2 for DVDs. It says "One audio track must have DD or PCM Audio." I didnt notice that before I made my DVD so I made the DVD have only one audio track as mpeg1-layer2 (no AC3 or PCM tracks). Well I guess I got lucky because, in my cyberhome chdvd 320 it plays perfect. My question is will other players have problems with playing this DVD and should I start making DVDs with AC3 audio instead?

the information you read was speaking i'm sure of maximizing compatibility of your dvd video. DolbyDigital (AC3) is the most compatible format to put your video in because all dvd players can play it. with the mpeg...you may run into problems with some dvd/receiver setups

Technically, the primary audio track must be LPCM or AC3 for NTSC DVDs, Layer 2 is optional. However, Layer2 audio is legal for PAL DVDs.
Since DVD player manufacturers use the same chipsets, all DVD players always support Layer2 as primary audio track, even though a few DVD authoring software will re-encode the audio in order to be 100% compliant with the NTSC specification.

I've used Layer 2 only for a lot of NTSC DVD's with no problems. Something above 90% of US DVD players will be OK with it. If you are worried, convert to AC3 with a program like ffmpeggui and use that audio during authoring for a little better compatibility and a smaller file size.
