I just got a new LG Plasma TV and connected my xBox via HDMI for the first time. Game play is fine at around vol level 10-12, but I have to turn it up to level 45-50 to hear any DVD I play. I have looked into this on other forums, but I have no other attached equipment, no stereo, no mediaPC, just xBox and TV. I have look through all the settings and tried all 3 HDMI ports on the TV and it's always the same....I love the picture and don't want to go back to my RWY RCA cable. Any advice would be appreciated.
