    It's as if Memory is Not being Freed Up and a Reboot Frees up that Memory which is really not being used but tied up and Released.

    My PC works the same way as it Slows Down and I Reboot it and it goes back to being Fast.

    However, all 5 of mine don't even Bog Down or exhibit any problems whatsoever other than Slow when Changing Channels (I don't surf or watch much Live TV so I could care less about that) which is due to the HDMI Handshake.

    You need a better PC!! :) My iMac hasn't been restarted at all except when I go on a trip or have applied an update requiring a restart.

    As to your operation of HRs, well I'm glad your glad! I'm of a different opinion.

    I did the NVRAM flash clear on two previously very slow HR21-700's the other day and it made them quick again which suggests to me memory management is at least part of the problem.

    It has been a very real problem for many of us for a long time. I have had consistent speed problems on my HR-20 and HR-21 since late 2008.
    I was this close to tossing the HR-21 out the window. It was unusable. Since then, the HR-21 has actually become faster than my HR-20. There is no rhyme or reason and I have tried EVERY SINGLE tip posted to these forums.
    I find it odd that people didn't start seeing problems until the HD GUI because I have had them for years.

    I am very tempted to pull the trigger on the HR34/HR24, but I don't want to get screwed by D* again so I'm holding off until they get their act together. If they can't then I'm off to greener pastures. 3+ years is way too long.

    That's just it! It's not the computer. Components don't just slow down. Inefficient and poorly written software will continue to consume resources until a reboot is required. The more RAM and faster processor will only help delay or mask the problem.

    But I don't have to ever Reboot my HR24-500s and they continue to run Fast without any Problems and I am running the same Software as those who are experiencing Slowness or Sluggishness, so it can't be the Code.

    The only thing I have done different than others is the Replacement of my Hard Drive with one that is Faster and has a Larger Cache which reduces the Paging Process which is the Slowest Process of a PC.

    IOW, if you add new hardware to them, they will perform properly. Pretty damning of the hard drive selection D* made when they put these things together, isn't it?

    And that again points to the problem of expecting a software fix to actually fix a hardware deficiency very well too.

    Couple those two with the history of software developement with D* and it paints a not so pretty picture.

    My experience is that the DVR's are much slower than the non-dvr's. For example my HR24-200 is MUCH slower than an H24-200, and its maybe slightly slower if not the same as my H21-100.

    I do think the HDGUI did improve things, especially scrolling the guide. There's still room for improvement. 59e or whatever the last NR was made things slower. In fact a buddy of mine has an HR24-500 and his box was MUCH slower than my HR24-200. I even did the NVRAM clear for him and changed the scrolling option. I have the 58c or 5c8 (forget exactly) but its the new NR that is slowly rolling out in the early morning hours. I think this version is a little better than the last - especially scrolling through the playlist. There are still some delays bringing up menus and exiting. I almost wonder if that would be masked if there was some sort of feedback. Like the screen fade in and out. The transition effect would be an indication that the button was accepted and you are "on your way" to that screen. Whatever takes 5 seconds to bring up the menu , list or guide could be prefetching or loading while that transition effect is taking place.

    What is the CPU again in the HR24's? Is it this one?

    That is a really good in depth data sheet with pinouts, signal traces and everything. Worth a look if your into that sort of nitty gritty.

    The Chipset used in the HR24-500 is NXP (I believe but I am not 100% sure) and not Broadcom which is used in the other HR24 Models.

    Well, you have to wait more than 48 hours for the DVR to finish Sorting and Indexing the Guide Data for it to then respond as fast as it should going forward.

    You can not expect the Speed to be the same as soon as you have the Software Downloaded then it will be 3 days after the Download when all of the Housekeeping Activities are finished.

    I just dunno. I see no rhyme or reason to the things they do. Logic tells me they can't be stupid and be as successful as they are. Of course, logic told me the same thing about NetFlix.

    We've known for years that the HRs will run better with a large internal drive as opposed to the paltry stock drive.

    Could you all take a moment and read this post by cypherx? Note how he gives the full model number of each of his HRs. Is that so hard? Believe me, it makes a difference which model you're using. Lumping them all together as "slow" is bordering on the ridiculous.

    So then we're stuck with poor design decisions on D*'s part since opening the box and replacing the drive is a no-no according to D*. Or we can just do it and hope they don't catch it when you send that box back after a failure and you forgot to switch drives back? Or notice that the box has been tampered with?

    Again, pretty damning of D*'s design and support decisions. That is sad.

    And no, not all of us knew that changing out the poorly spec'd drive with a much better one was the fix. I suspect that most D* subscribers aren't aware of that either. 'we' assumed that D* was designing a box properly. Seems we were all wrong.

    I don't think D* original design was bad since Tivo is able to run on a HR22 with no problems. I think that D* has added so much crap to their original design that is has driven the paging rate up and caused bad performance. The best fix for a high paging rate is to add more memory but since that is not possible, a faster disk drive will help the problem.
    D* needs to either make all these so called features optional so we can turn them off or provide us with a new larger more powerful DVR that will run all the crap they have added.

    I don't think a feature causes the system to be slow. If you don't use media share, pandora or YouTube, they are not taking processor cycles.

    I'm curious when they are going to fix the slow performance you get if you launch TVApps on a Scoreguide enabled channel. That was also a problem in the SDUI. I believe Scoreguide, TVApps, active and game lounge are a part of NDS MediaHighway (3rd party). So likely that isn't fixed (or upgraded to HD graphics) because it involves a lot of time an effort with a 3rd party.

    Like I said earlier my H24-200 is blazingly fast... But there's no hard drive or DVR functions.

    I suppose you get that info from the same people who told you the next release is going to be faster. That's just a symptom of poorly written software because anything the receiver needs to do, should be done in the background and shouldn't affect any normal operation.

    Since you get so many insider information, mind you telling me why with the new NR when I power up the receiver it outputs 720p despite that resolution being not checked in the display setups?
