    I don't think they have a "native" setting, do they?

    The 922 apparently doesn't do native.

    It's not HD, though; it really is just a somewhat simplified version of the current GUI. I don't think it's necessarily a reliable indicator of what the HD GUI will look like.

    I hope there's an option to opt out of or retain a non HD one. I want speed to access my programs over beauty...

    I suspect they'll choose a compromise resolution (say, 720p)...something supported by all HD devices. Only speculation.
    Unlikely. They have worked for years to get the UI consistent among all HD devices...and probably won't deviate from that approach.

    I think you've missed the question:
    What happens when the receiver is outputting 480i/p?
    To take this a step further... what happens with 480 and original format [4:3]?

    Upconversion?

    No different than playing a regular DVD in a Blu Ray player.

    OK, what happens when you are watching a *cough* SD *cough* channel with native on at 480i? The receiver is outputing 480i to the display. The GUI can't be 720p while the PIG is 480i...

    Couldn't the PIG be upscaled as well?

    Who says the HD GUI can't be faster? Maybe there's some hardware acceleration drivers that once utilized can really bring out the performance out of the processors. Think of a freshly formatted PC. Can you play some intensive graphical games on it? Maybe... but most likely the performance is horrible. Once you install the correct graphics drivers for your video card, then the hardware acceleration is on and the graphics performance is improved 1000 times.

    I know talking to someone at Motorola who works on Cable boxes, says that those new DVR's (the Motorola DCX-3400m) are very powerful, even though it doesn't look like it with the legacy software that cable companies have on there. They said that once the full tru2way java stack is enabled, operators can throw a ton of stuff at it, including hardware acceleration drivers that enhance the graphics output, allowing stuff like 32-bit color graphics with alpha blending, high definition graphics and animations. Now these use Broadcom SoC's but I'm not sure what chip powers DirecTV's arsenal. But if there are low level driver optimizations that can be done to allow the software to directly interact with the chipset and allow it to fully accelerate some of the mundane processing tasks that are currently taking up regular CPU cycles, perhaps the experience would be better? Tivo Premiere also uses a Broadcom CPU, which is dual core, but for some reason Tivo is only running it as a single core processor at the moment. Even at a single core, it's able to do an HD UI - but many say that it could be sped up enormously if the second core was to be enabled. Tivo is also using the very resource heavy flash, and on one core maybe that's why it's sluggish.

    I think you're still missing the whole point.
    The receiver can't "upscale" anything, when it's outputting 480i/p and in the 4:3 format.
    It would need to "down-rez" the GUI to SD.

    With native on and watching a SD channel, the receiver is outputing 480i to the display. The display is getting a 480i signal. In order to upscale the PIG, the receiver would have to change output resolutions every time you entered a menu or guide.

    People complain a lot now over slow channel changes. Imagine having to wait for the display to sync up every time you enter and exit the guide. :eek2:

    A huge section of early HDTVs do not support 720p. Ask Roku (supports 1080p and 720p but not 1080i) and AppleTV (supports 720p). Supporting only 1080p and 720p would be a bad idea. Supporting only 720p would be a horrible idea.

    It does take an eternity to change channels when the IRD switches res in Native. I've been to numerous service calls because the channel changing was so slow, only to find Native:ON :nono2:

    ..Maybe they'll just do away with the Native feature :p

    Yikes. I do wonder if that DMIPS is counting the Tivo with both cores active, or just the current performance with only a single core running? I used to have an iPhone 3G and it was so SLOW (the wife still has one actually). The HR24 is only marginally better than an iPhone 3G, and the other HR's are even less powerful? Wow then I don't expect too much, unless that is only raw CPU power and not counting any type of graphics acceleration co-processors or other specially designed ASIC's that can offload some core processing.

    The Motorola cable box I was talking about earlier is between the Cisco RNG-200 and Tivo Premiere on that list. I almost think it has the same generation Broadcom SoC as the Dish 922.

    My iPhone 4 feels really fluid and smooth. I guess the iPhone 3G was great for it's time, but as software got more complex and iOS updates carried more weight, they really did slow down these days.

    It wasn't necessarily a suggestion. Just a thought. If Native is a deal breaker for the HDGUI, which do you think will be more likely: The whole HDGUI thing is scrapped (forever and ever) or they just delete the code for Native to eliminate the whole issue? !Devil_lol

    It depends on your setup. It's just a split second longer on my setup...I prefer it on.
