What happens if you just Import the .VOB's into PrPro CS4.1 (or CS4.2)? If the DVD is 100% DVD-compliant, it should Import perfectly, and no need to change file extensions. Also, consider that the MPEG-2 content in VOB_01 might be very short, as there could be Menus and other navigational material in it. That is why all Menus and their Assets can ONLY be 1GB in size - it has to fit in VOB_01.
Thanks for the info Hunt. I will likely need to use the demuxer and a 'combine' the audio and video on the timeline. This footage is being mixed with stills and .mov footage from a different source.
In answer to your question:
The same thing happens when I attempt to import a .vob. In this case, the file info was posted after my inquiry. The file size is 200meg. The first 5 seconds of the audio is 'conformed' but not the rest. (The same thing happens with a different .vob of 189meg from same DVD.) Why?
In your workflow I miss one thing. You import the VOB. That's good. Now, missing is having a cup a cup of coffee. Next you start editing.
The missing cup of coffee could be the problem, because PR needs to conform the audio and create PEK files BEFORE you can start editing.
Yes, I ALWAYS have that cup of coffee (decaf, if I will then be editing... ), as Conforming and PEK generation can take some time, depending on the Duration. There is a little blue (in most PrPro versions) progress bar at the lower-right of the GUI. On really stout systems, some can actually edit during this Conforming phase, but most often, the program, or system will lock up, OR the CFA and PEK will only be partial.
Now, if you have been very patient, and the blue progress bar has completed for EVERY file Imported, and you STILL get truncated Audio, I am at a loss, as to what is halting this process.
IIRC, upthread you mentioned that the DVD was of your creation. Do you recall how it was authored? Also, you are copying over the VIDEO_TS folder to your HDD, and Importing from there, aren't you? Trying to Import from a DVD in the drive has caused issues for many.
Just thinking aloud here, and good luck,
Should it come to this, here is a FAQ Entry from the Encore forum on ripping from DVD.
I also wonder if you can rip just the Audio in Audition. I use it for CDA (Audio CD) material, but do not recall doing so from DVD-Video. If you can, you could then Import the resulting WAV into PrPro, and just drag it to the Timeline.
Might be more than one way to "skin this cat?"
