I have a 4 room setup that was installed earlier this year, every once in a while one or all of them will just freeze up, or they will just go blank than say that the channel is not available, like premium channels or a network channel, when clicking onto the guide, those channels will not even show up in the guides list of channels, than I have to unplug them and have them reset. After the reboot they return to normal. I have noticed that there is a lot of talk about upgrades to their receivers. I don't have any of them fancy receiver with tivo or HD, its just a simple D10-200, but when I look for a system upgrade date and version reads: 5:00pm Friday 3/22/2002 0.8.30. I am just wondering if this is the latest version for this unit, since I am not connected to a phone line, am I receiving any upgrades without being hooked up to a landline, I don't have one and don't want to spend the money for one. Does anyone know if this is the latest upgrade for this unit?...Thanks
