I watch mostly HD channels ,but the few times I turn over to SD channels I have to make sure I have remote handy as the Sound just blasts really loud .Is there a setting on my 722 that can fix this,its just not a little loud ,its very loud.having nieghbors on the next wall in my apartment is the biggest issue with this as I dont want to wake them if I accidently turn to a SD channels and cause sound to BLAST.
