Since I don't have any dvd's like that I am just guessing. Is it possible to play them and capture them instead of ripping them? When I have odd formats like that, or odd fps rates so that no matter what I do the audio is out of synch, I capture them through my Canopus analog to digital video capturing hardware. Then what is on my hard drive is a DV AVI standard.
I go out the DVD player, or video player, or camera, etc., to the Canopus to the computer. Everything stays in synch and the quality is the same as the original source.
It sounds like you need an option to downmix the audio track inorder to rip it.
Or is this when demuxing is the answer? Seperate the sound track completely? A bit daunting but doable. But if its copy protected, can you even do that? I'd be quite frustrated.
Sorry got ahead of myself. Well if they rip to the hdd and play fine, maybe you can demux the audio/video tracks? Certainly technically more challenging but there are several sites that have the information and how to steps. Then remix the audio to a standard format and then put the video and audio back together.
Thinking out loud here. Sorry. Once on the hard drive have you tried something like Nero Recode to remake the a new DVD and then re-rip what Nero makes to make the iPop file? I have just gotten DVDFab Platnium so I do not know its compression/recode/make DVD stuff. I do know Nero.
It seems you need a step to change the audio tracks from what it is to a more universal standard format.
Before I posted it I wanted to check. With Goldwave I can import a *.vob file and Goldwave extracts the audio track. Then I can do what I want with the audio track. Of course I don't know if Goldwave can read the HDAudio track you are dealing with.
And while I can't easily recommend Pinnacle's products with Studio 9, they are now getting ready to release version 11, I can import ripped DVD titles off my hard drive. Then I can use Studio to make a AVI, WMV, etc. file. I just tried it with a Simpson rip. So you might be able to, once its on your hard drive copy protection free, import the ripped file into a video editting package and remake the file with a standard format.
