Okay, I know this is nit-picky but I'd sure like to know why my DirecTivo (Philips DSR6000) is no longer making the familiar command sounds it used to (You know, the cartoon-like sounds when you navigate through menus or the "BONG" sound when you try to forward when there is no more green bar ahead?). My Tivo used to be connected directly to my projector. I lost the sound when I changed two things. I hooked-up my new B&K Ref 50 and switched audio from analog to optical. I hope someone has an answer so I don't have to go through a process of elimination. Thanks, Chris Never mind. I knew I should have searched the Tivo Community forum before posting this! If anyone cares - series1 units can't encode these sounds on Dolby.
