I recently authored a Blu Ray disc with 3 separate DVDs. I did not transcode to x264 as they are live event DVDs and I want to keep the interlacing. The issue that I'm having is that one of the dvds on the disc has sound but no video on leawo Blu Ray player and Toshiba bdx3500. The disc plays fine on my insignia Blu Ray player. Does this have to do with firmware or the way it was authored?
