i just bought this dvd player at sears for $80, when i play something the dvd player makes this buzzy noise and dvd movies and regular music cds sound lower than mp3 cds,i want to know if the sound is suppose to be like this cuz all my other electronics(dreamcast,vcr,dss) sound pretty loud halfway on the knob of this old aiwa dolby surround thing,do i have to change audio settings or take it back cuz having to lower down the volume when switching from dvd player to dreamcast is gonna get pretty annoying
