I'm one click of a mouse away from pulling the trigger on an 8200 from AC4L.com but have a couple of reservations. The first is that I understand that the 8200 takes a couple of seconds to lock into the digital signal when going through the layer change on DVDs. Secondly, I understand that the component video switching of the 8200 only allows output of a like input (i.e. component in, component out or S-video in, S-video out.) So my question is this. Does the upgradeability of the 8200 through the RS-232 port allow Marantz to address these "issues", or is the upgradeability only for future multi-channel formats? Any knowledgeable comments or speculation apprecialted.
