I was expecting this tonight overnight, but got it last night!
Permanent Guide Filter!http://splicd.com/pYzOQFpGPYE/2/18
Guide and box response is much snappier! There is still noticeable Guide Lag when scrolling, but not as bad as before. It is quicker to catch up. Overall performance is snappier such as Navigating the menus and utilizing options.
Noticed the diagnostic menu is gone for checking versions so I have no idea what the release version is. I can still get to the service menu pressing up after icon flashes, but pressing down does nothing.
Color scheme is OK, but I think the blue popped a little more. Disappointed it is not a 16x9 format GUI, still 4:3 pillar box. The black is fine, maybe I have to give it an adjustment period. Hopefully we will see it in 16x9 sooner than later.
DVR List still mashed and cut off. This really needs to be changed. They need to put the list along the bottom. If I get some time (I have 16 hour shifts this week) I want to do a mock up of how the list can utilize the space without cutting off names.
All in all from first look, not much has changed other than appearance and Guide Filter (the average sub is only going to notice the color I'm betting). I'm sure much was addressed "under the hood" and that's a good thing. I do like the A button for finding VOD which was buried within our crap line up here. Overall, this update was worth it simply to have the Guide Filter - big plus on that.
