Got it this morning and opted in on both HD-DVR's (HR22) tonight. Both DVR's see each other and that's fine. This is wireless, 5ghz ONLY 802.11n network Problem comes with playback (only HD since the DVR I use as a "server" only has HD content). I can play a movie/tv show whatever that is from the other DVR, and can pause it, but I cannot FF. If I FF I see the time bar move (but no FF'ing, the picture and sound are paused). When I press play the time bar goes back to the original time, the screen goes back, and then I am back on the info screen with an "Unable to access media." If I exit out to live tv and try to come back and play something from the server DVR, it won't play and I am told to check the network with relation to the server DVR. At that point, I can't watch anything off the server DVR until I reboot the server DVR. Any possible causes for the problem here? I'd love to use MRV, but FF for TV shows is kind of important. Thanks.
