Guys, I have three Sony VTX-D800 units in the house. When we first bought and installed them they seemed SUPER FAST - i.e. they changed channels very quickly and reacted promptly to key commands from the remote. They've now received a couple of "over the air" software upgrades - and I have to say they are MUCH slower to respond and channel swapping is becoming a bit of a chore (keep jumping more channles than you intended beacuse you assume the unit has not recieved the command - then it jumps several all at once!). Has anyone else notice this - and will it continue to get worse as additional features are added to the EPG?? Is there any way of remedying this? Personally I really think I'd rather do without the EPG and go back to a fast acting unit.
