mp3 is neither permitted nor frequently supported by players; for dvd x=704 is standard and very useful, because it often permits to crop without rescaling
Ah yes. :) BTW I think mp3 _is_ standard/supported for PAL DVD, just not NTSC. Can someone verify this?
I'm quite sure that MP3 is not supported. Only MP2,AC3,PCM and optionally DTS are supported.
My understanding is that you're right, except that MP2 was not included in the NTSC spec, and it's somewhat common to find NTSC players that don't handle DVDs with MP2 audio. Unofficially, there are plenty of nonstandard combinations that some players tolerate, and MP3 audio is just one of many. One thing left out of this guide: MPEG-1 video is allowed on DVD at resolutions of 352x240 (NTSC) or 352x288 (PAL). This isn't identical to VCD; you can use VBR and of course the allowed bitrate is much larger and so is the VBV buffer size.
