OK here is what to do. First all DVD audio disks use the wav format and the DVD must be burned in a special format. You MUST use DVD -R in order for it to work in the acura TL (or any acura). You can strip tracks from your DVD video disks, convert your MP3's to *.wav files. Your Acura does not have the ability to decode MP3 directly.
Here is what I use:
Go here ( This is a free program that you can use to convert your MP3's)
Click Download on the upper left and then download
Go here (there is a free 30 day trial but is inexpensive to get license)
Download DVD Audio extractor
this will let you strip any DVD audio track into the *.wav files it can do 5 channel DTS, 6 channel AC3 digital dolby and 2 channel stereo and generate the files you can use to burn you DVD's
Now they key is to burn with the following program. This will burn the *wav files you generated with the above SW and enjoy them in your ACURA
Download audio dvd solo (this gives you I think 5 free burns I purchased the Lisence and its only $34.95
I have no affiliation with any of this. Hope this helps.
