I have stayed away from MGM DVDs for long time due to the poor quality mastering. Recntly I rented a couple of MGM DVDs from Netflix, "Out of Time" and Hotel Rwanda". Both Dolby 5.1. I have an oppo dvd player connected to a Sony HTDDW670 HTIB. I found the audio levels were too low in both DVDs compared to other DVDs from WB or Columbia Tri-Star. I am connecting through the coax audio. Has anyone else noticed this?
