I recently upgraded my Yahama RX-V992 rec to the 1050 after reading many reviews..however I now have an audible hum/buzz from both of my subwoofers( front is JBL 10 in and rear is Definitive Tech 15 in)..this hum is louder from the JBL then the Def Tech..they are connected via a Y connector...also I have noticed that.... on several DVDs that the front panel reads Digital in red as well as dolby pro logic.....the new Spiderman DVD reads dolby digital surr6.1...but the others do not...one more final question....another reason I purchased the 1050 is for the added feature of DTS...I played the EAGLES DVD which is recorded in the DTS format but when the DTS logo comes up on the screen all I hear is a low pitched hum..when I switch to PCM then the 1050 reads pro logic....thanks for the help......
