I’m pretty much an idiot when it comes to tech stuff, so I apologize in advance if I misunderstood your questions.
My profile is iPodTouch. That’s what I selected from the dropdown box on the conversion settings screen. (But maybe I misunderstood what you mean by profile?)
I was able to play the file on VLC fine, including sound.
By DVD source, do you mean the DVD I was trying to backup? I tried four different discs, but the latest I tried was The Dick Van Dyke Show, Season 4, disc 1.
