Hi all , I'm 24hrs in on the upgrade to the X-1 platform and thus far the only issue was the having to record shows using the smaller tuners around the house in order to pause live tv, I tested this last night on the main dvr (hub or whatever you want to call it) and it worked just fine. I haven't had any issues with any of the stb going back to 720p after entering there explicit 1080p settings even after shutdowns, the main dvr is hooked directly to the display with optical for audio, could be for those of you that do does your receiver or pre/pro have a pass through option?
Now as for its performance I'm extremely impressed as it seems they've put together a well thought out interfacing system that's intuitive and very easy to figure out and navigate, even the wife is tweaking her settings
picture quality is first rate with some good upscaling going on. Overall i'm impressed with what they've done.
