No, my biggest issue with the new layout is simply how hard it can be to access things one once could get to quickly. There seems to be no rhyme or reason to the Windows Phone 7 / Windows 8-inspired layout, and although that might be a pretty cool concept it ultimately leaves me fumbling around across screens like a baffoon because Netflix is in the "Apps" category, instead of "Video".
Also, Windows Media Center for Xbox 360 sucks ass. It sucked ass before the update, and it sucks ass now. Why is there no Pause command? Why, when I hold down the right trigger which by default skips forward X seconds, does the scroll marker shoot to the beginning or end of the video? I either tap the trigger 60 or so times to find the part of the video I want, or hold the trigger down to get to the unwatchable end of the video, the last part that only leads back to the main menu, that no one would ever, ever, ever need to have a dedicated fucking command to get to. There is basically a command assigned for "go to the very end of the video", but not a pause function. IT'S THE END OF 2011 FOR FUCK'S SAKE.
WMC can really get me angry. Apparently.
