Greetings and thank you for your response,
The format is NTSE and the music was a Itunes download, saved to a disc, allowing me to save to Windows Media Player. My standalone DVD is not subject to region codes, so any DVD audio disc will play on th unit. The disc will play on my computers, both movie and music. I've tested other burned family movies (made by others) and theirs work fine in my DVD player. The first time I burned and saved movie to a DVD-R 1-16x 4.7 GB, disc which resulted in no movie or music on standalone DVD. I tried again using a Memorex CD-RW disc, 1x-4x, and I got the movie, but no sound. However, the other home movies I tested are stored on DVD -R 2x, 4.7 with excellent results. You asked what type audio in my DVD and I'm not sure how to determine that specifically. Hope this information helps. Please don't give up on me.
