No Audio When Converting Blu-ray Rip to DVD AVStoDVD

[Altern881]

I have some .mp4 Blu-ray rips that I'm trying to burn to DVD. I'm outputting them as .iso, then burning the resulting image. When I mount the image, I get perfect video, but no audio. There's also no audio once burned to disc. When I try playing it in my 360, I get this garbled/ squawking audio. It seems like this is a somewhat common problem with audio from Blu-ray rips, but I can't figure out how to fix it.

What is the audio in the mp4? Identify with mediainfoxp.

I've had issues in the past when trying to convert DTS HD MA audio from Blu-ray to DVD in AVStoDVD. Not sure why you would have this audio codec in an mp4 however, as most convert to ac3 or aac.
You can try changing the default audio converter in AVStoDVD from Wavi + Aften to one of the FFmpeg modes.

When converting straight from the original Blu-ray to DVD-video, I've switched over to BD Rebuilder. But from an mp4, AVStoDVD should be fine.

I'm re-encoding it with different audio encoder settings to see if it helps, I'll let you know when it's done. In the meantime, here's the info.

I'm still not getting any sound.

Let me guess - this is anime, isn't it? Your audio uses (because whoever encoded it is an idiot) VBR (variable bit rate) and that's probably causing all kinds of nasty problems for AVStoDVD. I have never used AVStoDVD so I'm just guessing, but VBR audio would be a challenge for a lot of programs. And I'm not sure what the heck is up with the Sampling rate showing both 48 KHz AND 24 KHz. Bizarre. Anytime something makes no sense at all in a video, it's almost always anime. That bit rate is really low too so even if you fix the problems and get the audio working, I wouldn't expect it to sound great.

It's actually not anime, it's a copy of Crazy Stupid Love. I would use the original disc, but my Blu-ray drive stopped working, so I'm stuck with this.

Try opening the mp4 file with Audacity. You'll need the ffmpeg library for Audacity installed as well. http://audacity.sourceforge.net/download/plugins

This will import the audio alone. Then export the file as an AC3 file. Make certain to use 48000Hz in the output. This should give you an audio stream that will be compatible with the DVD you are making.

Next, import the mp4 file into AVStoDVD. You'll see both the audio and video streams listed there. Right click in the main window of AVStoDVD and you'll see some options, one of which is Audio Track. Delete the existing AAC audio. Then add the new AC3 file that you made in Audacity. Making the DVD should be straightforward from this point.
