The volume on the Z2 in general does not go as loud as i would like. Thats the first problem. Way to make it louder? Then when i watch a DVD on the move, it seems very quiet, with all the road noise. I have it turned all the way up and source level is turned all the way up. If i switch it by hitting AV and switch to the Library, it comes on like twice as loud as the DVD was (without changing volume settings) Anyone have similar situation? Solutions? Thanks.
