I recently got a new sony blu-ray player and yamaha HD receiver. My dvd's which were created from converting an avi into dvd using visual hub won't play sound through my new setup. Other dvd's (originals and backups play sound/video fine). The blu-ray says the dvd's which I'm having sound problems with are Dolby Digital 2.0 / 48 khz. Is there maybe a different way in visual hub i could try formatting the sound to correct his problem? Any suggestions are appreciated. You guys have always been great in the past.
