Is MPEG-1 Audio Layer2 16 bit 48 kHz sound DVD ready?

Is MPEG-1 Audio Layer2 16 bit 48 kHz sound DVD ready? That is the audio format my Sony HDR-FX1 records, so I was curious if this can be burned straight to a DVD along with the MPEG-2 video the camera shoots.

15.4-inch MacBook Pro. 2GHz Intel Core Duo. 2GB., Mac OS X (10.4.7)

I have never used that format, but this is what DVDSP User Manual says about (page 78):

MPEG-1 Layer 2 Audio
For DVD products in PAL, MPEG-1 Layer 2 audio is compatible with all players. For NTSC markets (North America, Japan), most (but not all) DVD players support playback of MPEG-1 Layer 2 audio. If you create NTSC titles using MPEG audio, be aware that there may be problems in playback on some players.
If you want to ensure that your data-compressed audio is compatible with all players for NTSC, using the AC-3 format is recommended.

How are you capturing and editing from the camera?

I have the camera and if you capture and edit in Final Cut or iMovie you can export it for use in DVD SP. Usually the best way is to export it in an uncompressed format and compress to A.Pack/Dolby (the audio) and m2v (16:9 aspect which makes a 720 x 404 m2v for SD discs)

You can control how the audio is exported from iMovie or Final Cut but if you have not changed anything you should be good to go.

Little Endian and Big Endian is how the data is stored with the most signifcant byte on one end or the other (taken from Gulliver's Travels and how the egg should be cracked). For the most part you do not need to concern yourself with this (unless you like finding out about those things more) it is transperent in your workflow on the Mac using these apps.

i just dont want my audio format changing ... i capture in final cut pro 5.1.

Final Cut - and, for that matter, most audio editors that I'm aware of - will only work with uncompressed sound. This is because it is expected that you will want to change the content in some way, whether by changing levels, mixing tracks together, or equalising/treating the source recordings. This is not possible with compressed sound: it is really just designed for playback, and uses quite serious acoustic masking techniques. The same does not apply to frame-based compressed video (like DV or HDV), where you can leave it as is while editing for a lot of the time.

Are you sure that your camera doesn't record uncompressed sound as well as the .mpeg1? If so, it would be natural for FCP to transfer this, and ignore the compressed version. Alternatively (if it doesn't) the sound is being converted to an uncompressed format on the fly so that you can edit it.
