There are a number of threads relating to the MRV issue where DVR's intermittently "disappear" form other receiver’s play lists. Many of the threads recommend putting all receivers on Static IP to resolve this issue. I have done this and, wouldn’t you know it, my MRV solution is now stable. I have two questions. 1. Is there somebody on this board who can provide a technical reason for this? My lease refresh is set at 1 hour, but I my router was not chaning the assigned addresses, simply renewing. Also, under DHCP, I could not necessary get the system to a state where all boxes were visible to all other boxes. Under static IP the system is rock solid. 2. Since this seems to be a solution to a common issue, why doesn’t DTV simply make this recommendation? It could save frustration and improve customer satisfaction. BTW - My nextwork is DECA to 4 recievers with a ICK connected to a Linksys wireless bridge.
