John,
As I mentioned earlier, I have made many a DVD-A using Chrome to be used in my Acura's. Some from quad conversion, or SPEC conversions, and files run through the Surround Master. They all work fine, although for some reason the titles never appear in the menu's on-screen in the car. I've had 5 Acura's since 2004 with DVD-A players in them and they've all been great. The very latest models are deleting all disc based players, but there are many 2014 models that still have ELS DVD-A players in their Tech Packages.
As far as other manufacturers, other than those posted by member here in this forum, I really have no idea.
FYI - I tried every which way of getting a DTS file to play via USB in these cars, and it just does not work. The DTS Decoder in the ELS unit apparently does not have anything to do with the USB audio input path. Shame, really.
I am trying to avoid using Chrome because it forces me to have encode each song using Surcode MLP..
Will the ELS DVD-A player play non watermarked DVD-A copied using say DVDFab onto a DVD-R?
