Muxing LPCM for DVD

I have an m2v and a WAV file that I need to mux together for DVD, but Mplex and every other program I have tried says that it cannot mux the WAV file. I know that DVD's can have LPCM audio, so is there a way to convert WAV to LPCM or a muxer out there that will multiplex these two files?

Sure you should be able to mux a WAV file for DVD with probably any authoring program. For example, IfoEdit is one of the simplest. For your purposes, WAV and LPCM is the same thing. Important part is the WAV file parameters: it must be encoded at 16 bit with 48kHz sampling rate, otherwise it might be rejected, which is most likely what's happening in your case. For example, if your source is a CD track, it would have 44.1kHz sampling rate. Almost any sound editor including the one that comes with Windows can convert a WAV file to match the DVD specifications mentioned above.

Actually the audio is 48Khz, 16bit, 2 channel. It's the original audio for the movie, but it had to be decoded for some reason or another (I haven't worked on this project for such a long time) and I've tried re-encoding it, but the nuances of the audio are lost, even at high bitrates(using both AC3 and MP2), and so I would perfer to use this manner. I tried using Mplex to multiplex these together, and it wouldn't recognize the WAV file. I hope ifoEdit will. My authoring app is dvdauthorgui the aug 11th release. Thanks for your help!

An update: I tried both VobEdit and IfoEdit, and neither of them will mux these two files. I don't think you understand that these files are not ripped from a DVD, but are actually files that I captured and re-encoded. There is no option in either of the two apps I just mentioned that allows me to multiplex two files, the closest option is to remux an .m2v, but that doesn't put the audio with it. Any other options that I have?

IfoEdit will mux them, using the "DVD Author" option. (But FWIW, I once tried this with IfoEdit v0.94 and the result was unplayable on my system.)

You may want to try muxman. it can accept lpcm and i presume it can in a wav wrapper.

@fcchandler I never saw a "DVDAuthor" option, but I will look for it. @Trahald This is just hilarious, muxman accepts the WAV file, but it doesn't accept the .M2V. Any guesses as to why? (It's DVD compliant, as far as I remember) +++EDIT+++ I have found the problem with my M2V: apparently, its been IVTC'd to 23.976, but I've been told that (some) DVD players will accept that. So, is there a workaround for muxman or another app that will mux this? Full stats: Video: 720x480 23.976 ??kbps (I'm pretty sure its DVD compliant) Audio WAV(LPCM) 48KHz 16bit 2 Channels (stereo)

the mpeg reading 23.976 isnt legal for dvd.. it would have to read 29.97.. you should use pulldown.exe or restream to fix the headers to 29.97 and make sure rffs are applied to bring decoding fps to 29.97. the muxman.log tells you the code for why an asset failed the readme explains the codes

I looked at the logfile, and it confirms that the error is the framrate of 23.976. So, using pulldown, would I just run it default without any options for it to do what I need it to do? I'm sorry, I have never worked with anything that was 23.976 and destined for DVD. So, if you could point me to a guide, or give me a little help, it'd be very appreciated.

This will do what you want: PULLDOWN "inputfilename" "outputfilename" -drop_frame true
