    I switched from the TIVO HD version which had it and to this day that is the main complant I get all the time from my wife. "Why did we get this, I liked the other one better. I could flip channels and rewind on it"

    This is not true. It does maintain dual live buffers. We just can't access the 2nd one. It has been seen by several people on here.

    Here is how I found it...

    Tune to Channel A, start recording. Then change to Channel B. Leave it on Channel B for a while to let the other show record a bit. Then go into list and start watching the show recorded on channel A. When you reach the end, select to Delete Now. It will take you back to the List screen. Immediately press Guide and go to Channel A's listing. Select record on the current program (make sure its one that isn't just starting) REMEMBER... the live buffer has been on channel B this whole time. After you select record on the Channel A program in Guide, hit list and begin watching the new show. It should have recorded from the buffer. At least it has for me on 2 occasions durring baseball games when the recording ended, and Ihad to select the Post Game show to see the previous 30-45 minutes that got cut off.

    This means it does maintain both buffers, but once you tune to a new channel (or previous channel) it clears out the buffer first.

    wrong, the hr2o is incapable because of the way resources are routed in the unit,

    now the bsiness reason why directv has not implemeented dlb (if they had a dvr capable of it) they are trying everything to be not like tivo, which is not a smart descion,

    they should implement all their features ( in a non-illegal way) and add tons more.

    which then they could say .. tivo has less than us

    then youd see no tivo people still wanting tivo

    i would not call head engineers bull in bulk of major electronic makers.

    and the lock-ups you are touching the surface of why the hr20 and r15 are incapable of dlb,

    afterall they was tested and ...............

    I can and I will, if that is who you've really talked to. Yes, bad software can make things not work. That is why it is called bad software. But that is not what I'm calling the HR20 software. It CAN DO DLB. At most it might need a bit more tuning and cleanup. At least, it might just need someone to turn DLB on again.

    Think about how much work there is recording two items and playing back a third. Think about how much less there would be just buffering two live streams. In other words, think for yourself with the evidence you have right in front of you. Anyone telling you the HR20 is not capable of DLB is wrong. There is even a work around (ugly as it is.) So it must be possible.

    And if you have contacts at -100, have them can the "engineer" you're talking to and have them hire me. :)

    Cheers,
    Tom

    Welcome to the forum jlanger! If you and your wife feel strongly about DLB. You can copy and paste one of the letters and mail it out.

    I think with time... maybe a long time.;) DLB will come to the HR20. Right now I'm sticking with the HR10 until I can't use it anymore or HR20 gets DLB.

    I haven't seen this new wish list link posted in this thread... But be sure to add your thoughts to the wish list so that there is more evidence that DLB is important...

    Count me in as one of those "idiots" that just assumed that the HR20 would have DLBs. I remember thinking "I cannot F'N believe this" after spending several minutes pressing the down arrow.

    (I didn't read this entire post, so if someone else suggested this, then just ignore me)

    I would like to have dual buffers, but yet I also like the 90 min buffer. I think that if D* can ever add duals, then since the HR20 already has the one 90 min buffer, maybe they can make an option in the menu for having dual, or single buffers.

    It might require a reset to get it the way you want, but at least it would please everyone, and it would become a superior unit.

    I spent a good 20 min. trying to flip tuners when I got mine too. I knew it had two tuners... there had to be some way to switch between them! Joke was on me!

    Amen brother. If it can record 2 and play a 3rd, everything works in HW to support DLB. Period. It is passing all of the information around that needs to be handled and, since almost all processes are I/O bound, it has satisfied the short pole in the tent. Switching between live buffers is merely a matter of changing iNode references, and since since you can change channels at will, all of the MPEG framing info is available in small time slices. To recap, all of the data need can be passed (biggest bottleneck), decoding streams are re-enterant, and the CPU can handle 3 simultaneous streams. Ergo, everything needed for DLB is in place, it is merely a case of doing the right thing in software.

    For the record I am an engineer who does HW design, but I started life as a SW engineer before I saw the light.

    I'm asking this question in all seriousness. What is the harm in DirecTV telling us why they choose not to implement this?

    We have been told many times that there IS a reason they are not doing this, and it will become clear to us all at some point. So, what is the big secret? Why can't we, the paying customers know? How about just telling us, IF you are planning on getting to it at some point? Is that giving us too much information?

    I'm also a software engineer, and will not pretend to know the complexities involved in implementing DLB. What I do know is that the company that I work for would not just let our customers sway in the wind while we play keepaway with our little secret, or at the least give some kind of explanation on what is going on. I'm sure they know whether or not this can be done, I understand they don't want to give us the details on when/why, but how about just if they THINK it will be done? Throw us a bone. I don't believe customers that are spending the kind of money we are for this service are asking too much. Seems very arrogant to me. Just my opinion.

    Maybe they have no intention of implementing DLB and would rather string along their customers instead of losing them. I assumed the Hr20 had DLB when I purchased it. I was not happy when I learned that I had purchased an inferior product without DLB. I then learned from this website that it was possibly going to be added later. Now I wonder if this information was put out there to satisfy some upset customers.

    I miss DLB as much as anyone. But I knew it wasn't in the HR20 from the first review. I knew it when I made the decision to buy it. DirecTV never hid the fact that they didn't have DLB implimented. I see no arrogance in there not giving there competitors any traction regarding the availability or non-availability of DLB.

    However, what I do find arrogant is that they released a half-baked, very buggy product and made DirecTV customers unwilling beta testers. Now that I have had two HR20's for about a month, I can tell you I have never, ever owned a product that was so buggy. Major bugs, little bugs, known bugs, unknown bugs, new bugs, old bugs. You name it, and they are there.

    More than arrogant. Inexcusable is more like it.:mad:

    Last "bug" I discovered was 3 days ago when it told me it had downloaded new software (it hadn't) and was locked up on that screen. Rebooted. When the HR20 came back to the guide, I found it had erased my favorite channels. Bad enough, but then I discovered to my great consternation that History, To Do list, and ALL of my shows (the disk was close to full) had been deleted from the receiver.

    How's that for a bug?

    Other than a feeze up about every 6 weeks, mine has been rock solid. No missed recordings, season passes work great.

    DLB are the only thing that hass kept me from making the HR20 my 'go to' receiver. I still use my HR10-250 (TiVo) as my primary receiver. IT just works the way I am used to. But no DLBs are the only knock I have on the HR20.

    Nobody is being strung along unless you want to be. Earl has said in no uncertain terms to not count on DLB to ever be put on the HR20 and if that is a #1 feature for you then you better start looking at other options. He's said it multiple times.

    So if you are "being strung along" on the 2% chance DLB gets added to the HR20 in 1-2 years then it's your own fault. Seriously.

    Then again, my HR20 only deleted everything once. The problem is, I won't know when the next time will be. I don't know about you, but I record things I want to watch. My play list is the only thing I watch from.

    So maybe you will be lucky and your shows will never be wiped clean like mine. But aren't you happy in the knowledge that this CAN happen?

    I've had TiVo's for close to 8 years. NEVER did any of them ever delete anything I didn't tell them to. NEVER did any of them fail to record what I asked them to.

    Is this too much to ask of a "state of the art" DVR?

    Not sure if you did, but did you report it in the issues thread?

    Secondly, if this happens it usually means a bad hard drive or some corrupted sectors. If there is a bad hard drive the HR20 instead of just dieing and refusing to boot up will try to recover. In doing so a format may happen which will unfortunately wipe out information on the drive.

    So the HR20 way is to try to recover from such errors so the user can hopefully keep running vs. Tivo where you get constant lockups, GSOD and so forth. Either way you may lose your programs, at least the HR20 way you can continue to use it while you wait for a replacement.

    So that's a long way to say that your hard drive is probably bad and it may happen again. Call up for a replacement. Start a thread on this if you need further help.
