Roxio Toast Titanium 17, burning DVD to an external Samsung Blu-ray recorder. iMac i5 with OS X 10.14.6. Burned both HD and standard DVDs and get the same results – it doesn't sound like the audio from the movie I made in iMovie 9, it sounds like a background track, quiet, with like a TV in the background or something. Both times. Play the regular MOV and it works fine. So weird. No clue where the audio is coming from. Might try exporting MP4 if I can. Any suggestions would be helpful. Thanks!
