I have put a USB Thumbdrive into my 622 and transfered jpg files of the family onto the dvr. I don't think that the 622 supports anything other than that for the USB port.
DishComm allows multiple receivers to share one phone connection through the power lines.
Maybe someone should let the engineers at Dish know that pretty much anyone who can figure out to get an Ethernet jack to their Dish receiver can probably also get a phone jack there as well. I can't believe that they are using Ethernet capabilities to piggyback a phone line for PPV authorizations and validating equipment on your account.
While those features are neat, I don't think that Dish ever makes promises on that stuff. Sure people here in the forums speculate, or some trade show interview may discuss things that they are working on, but room to room DVR was a Voom feature, not Dish. I also don't remember a PC to Dish MM content feature either. But I'd love to learn more. (The reason I'm here everyday ).What about some of the "long-ago" promised capabilities, like sharing stored programs to other PVR's in the house across Ethernet, downloading multi-media content from your PC, etc.??? Wouldn't it make a lot of sense for the PVR ro access a Media Center Server to spool content from??? When will Dish start to deliver on the promises embedded in the technology?
