And, I really wanted to get this processor, but I did not purchase one because of the issues with DVR's. What I don't understand is that this processor has had these issues for a good long time, and yet, the issues still persist. Very disappointing - I just don't get it.
Well, it's NOT unusual for a "boutique" (small company, Non-Japanese) AVR-Processors to have CODEC lock/unlock/mute issues.
ARCAM seems to have solved theirs with long CODEC mutes. A little annoying when you are not used to it, but once you are they are very effective, even if it might be considered a "lazy?" fix.
Anthem is actually pretty good. They do NOT do long CODEC mutes and are VERY close to almost, nearly eliminate the issue. It took them until SW 50.23 to get it down pat. That's a year and a half from release. But I have other issues such as static, strange "pressure" type noise at the end of DVR programs.
OTOH, Cary seems to have VERY LONG CODEC lock mutes but I still had REALLY bad CODEC lock/ unlock POPS!! I mean REALLY bad.
Just to let those confused......ALL CODEC changes/losses/etc involve what would be those loud POPs/crunches/etc. To overcome this they MUTE the sound for a period of time. You can imagine how complicated this would be with all the different equipment, processors, timing, bad signals, bad HDMI codes, etc.
When you hear a POP it is usually because you are catching the end of a CODEC lock, loss, etc. Sometimes the mute doesn't happen, or is too late, etc, etc.
SO why do the Japanese seem to rarely have these issues? Well, first they are just "better" at it. (yes, I know, but hey I don't know everything) They also are more "willing?" to be less pure/or official about it. many "boutique" units seem to want to break CODEC at EVERY opportunity. Even a 30 second skip on a DVR will often lead to a short "no signal" message followed by a CODEC relock. THIS example is why DVR people are the most sensitive to the issue. Imagine every 30 second skip used during commercials involved a LOUD POP noise. POP POP POP POP POP POP POP POP. The Cinema 12 I had was like that, intolerable even for a few hours.
One way, I've noticed, the Japanese models avoid it is by being less prone to "drop" the current CODEC even though the CODEC is gone from the source. Such as a 30 skip OR pause of the DVR. I had an Onkyo, that even when I paused a recording on my DVR, with no audio the signal is effectively gone, it would still show the previous CODEC. Same during 30 second skips - simply did NOT drop the CODEC. Thereby avoiding the CODEC lock again and the possibility of a POP. THAT'S what i mean about being less "PURE" about it.
It's amazing that most reviewers seem to just ignore this horrendously untolerable issue. But I think many of them never use a DVR, it's all BR, etc. Where the issue is much less intrusive. I also think there's some "benefit of the doubt" that they will fix it later with SW updates. And some equipment is simply more prone to the issue like I "think" my TiVo HD XL, "maybe" seems to be. Maybe. I don't know, I don't have another DVR to test. But newer one's seem better. But then I've used the same DVR with Japanese models (old and new) and once again --- no issues.
