DirecTV's HD UI was a godsend to utilizing the service compared to the old low resolution, low color palette, clunky blue UI. I really like the look of the DirecTV interface and it is very professional, loaded with nice features and easy to learn. If I had one major complaint, it would be the screen draw performance and apparent lack of OpenGL 2D graphics hardware acceleration. What I mean is if you push menu / info or navigate on screen... many screens do not softly transition and seem to abruptly draw (or exit) after delay. I know we are not dealing with the sheer power of multi-core ARM processors, like those in our smartphones. From my understanding, DirecTV uses Broadcom based MIPS reference designs. Looking at Broadcom's featureset, they include things like OpenGL 2.0 and DirectFB (Frame Buffer) support. Direct writes to the frame buffer could really speed up the HD user interface and provide that little bit of finesse and polish that your accustomed to seeing when working within the UI of Apple IOS or Android JellyBean (Project Butter optimized 60 fps triple frame buffering). Think of the smooth page swipes and all the crazy smooth effects & graphics in games and applications. I just think if DirecTV would utilize some of these enhancements, hardware accelerate and better utilize the frame buffer, some of these performance hangups we see would be eliminated thanks to more efficient code and hardware acceleration offloading frame drawing effects from the main core processing. There is a real good demo of DirectFB running on Broadcom 97425 MIPS based platform here: http://www.directfb.org/?path=Main/Videos&page=0&video=ilixi_compositor_on_bcm97425 The video was rendered on the Broadcom MIPS SoC at 720p and its smooth as butter. If the DirecTV user interaction / frame draw routines utilized this kind of acceleration, not only would the operating system feel smoother with buttery screen transition effects, it would also optimize processing so the overall experience would be faster and more efficient. I'm not sure what the actual DMIPS numbers are for currently deployed DirecTV DVR's and HD Set top boxes... but there has to be some headroom for improvement. I do realize that the upcoming HR44 and future STB's will surely have more processing power to accommodate UI enhancements while providing speed and efficiency in accessing DirecTV features on screen. I just look at that new Roku box and envy the nice smooth interface, yet the system itself is smaller than any DirecTV receiver.
