    I'll let him answer, but I watched the same show with MRV HR21-200 to HR20-700. It looked great when it wasn't breaking up, but yes it did breakup at random intervals.
    These seem to be slightly different with this CE than earlier ones.
    "Before" the random glitches seem to affect an object within the scene [a person], but with the current CEs, my H21 showed dropped frames, and my HR20 would have the whole screen "sparkle" [white pixelation].

    Sometimes there were 10 minutes between breakups, and sometimes they would come in bunches. Video was quite good between breakups.

    I've always seen breakup's since day one using everything from wireless to powerline to hardwire to just two STB's connected directly to each other. Sometimes it's flawless, other times close to horrible with some 'breakups' looking like someone hit a fast forward button and the vidoe/audio was skipping. To me I see this more on certain channels with HGTV and Comedy Central being the wosrt and Showtime West being the best.

    Strange....we actually had entire 2 hour movies play using MRV without a single breakup or pixellation whatsoever. The "hiccups" were few and far between duing viewing on all 3 devices here over 14+ hours this past weekend on the latest CE.

    Interesting about the "all green" comment. In my situation, every time I check I'm "green." The only time I've had any problems was when I started crossing streams through my dual-connected HR21-200. Then I was able to actually lock up the network/DVR until I backed off on the number of streams. I'll need to run a DECA only test to see how those perform.

    However, in the single-stream situation I've always been quite happy with the results.

    I'm seeing this but in the 2 hours I watched there was maybe 3 or 4 instances (one was whole screen). In each of these cases, it was back to picture-perfect in 1-2 seconds. While I would still push for improvement, I find that to be within the tolerance level in my case.

    "Tolerance level" [for me] will vary on the show and where it happenes. If the show is something like Pineapple Express, it doesn't matter, but if it's something like a mystery, where I'm looking for subtle "clues", then it gets annoying.

    While the vast majority might be happy with it IMHO DirecTV needs to shoot for zero problems else other vendors, especially ones that don't have the same problem, can use it against DirecTV.

    Even though I seem to likely have some of the least reported MRV viewing errors here....I'd agree that there is still some work to be done, and also agree it needs to be solid, especially before goig mainstream.

    I do see some progress being made with each CE.

    I am more tolerant of brief picture breakups than my wife. I can watch an MRV show that has only occasional hiccups without a problem. My wife consistently asks "What is the problem, what is causing that?" If there are more than 3 or 4 brief hiccups in a one hour show, she can get pretty upset about it. It only bothers me if the hiccups interrupt something important, like the punch line of a joke. (e.g., breakups are less acceptable in a Leno monologue than later in the show).

    As VOS noted, what you are watching directly impacts the acceptablility of the brief hiccups. DirecTV must assume that you will always be watching something that is critical, and provide a product/feature that provides a satisfying viewing experience. For me, one or two brief hiccups in a one hour show would probably be acceptable.

    Sometimes I'll check the breakups by rewinding and re-playing the show. So far, every single time I've checked, the breakup did not occur on the replay (i.e., it was not received/recorded, it happened as part of the MRV process).

    I'm in the same boat as Carl. I can tolerate the brief "hiccups" every several minutes, but they drive my wife crazy. She keeps asking why I can't fix that!

    When I am really focused on a really good movie and the breakup occurs during a critical dialog to the plot or critical visual as other have said...it doesn't meet my expectations. If I was thinking of going to market with a function that had "occasional breakups", I would think again. Get it right before going to the mainstream.

    HR22 locked up today, and after reboot, I totally lost MRV. Unable to get it back, every time I try to pull up playlist on HR22 now, its either blank, or locks up again. Trying to pull up MRV with HR20, shows the ghost menu over the regular playing show. I disabled MRV on all units by Misc Menu, and now they are operating normally, without MRV, but network functions all appear ok, DECA wise.

    Had my first noticable episode of choppy HD playback yesterday since DECA was installed and last reset. HR21-100, served by HR21-200.

    MPEG-4 movie had several pixellation episodes, as well as some choppy playback.

    Tried another later on, and things were back to "normal".

    Agreed... There's nothing worse than a big moment in a show, or movie, being ruined by the picture glitching at the wrong time.

    I'm seeing it less and less but it's still there and I would say MRV isn't ready for the masses quite yet. This week's CE apparently tackled trickplay issues with MRV and did a pretty good job of making that smooth now. Maybe the next CE will tackle playback.

    I haven't seen much change with this week's CEs.
    Trickplay still does the "double skip" as before. SD playback is fine. HD still has random breakups.

    With the H21-200, the playlist has been easier to resort/open all folders, or at least has ended up displaying folders/contents much better [I mean there is an effective work-a-round].
