just got it up and running about 30 minutes ago. Had to do a software update (press red button + 02468) to have the MRV show up. Doing the MRV via the coax, no network needed. i can say that i miss the clock on the receiver lol but thats not a big deal.
Get a small digital clock and put it on your console. Works for me.
Pushing the Info button will give you the time.
