Pioneer DV-47ai and jitter

Harry-

Yes. There have been no signs of the chroma bug in my DV-45a. The DV-45a has a switch to shut off the video section.
It's never missed a beat on any type of disk.

My mods are basicly the same as Dan's transport mods, with the addition of drive/chassis damping, ERS and more filtering on the 5v rail.

Aloha,

Dan

Without meaning to hijack this thread, I'd like to ask whether anyone has had Electronic Visionary Systems (EVS) perform modifications on a DV45/47A/47Ai???
In the attached link, they charge 3-4X what Dan Wright charges but they do list their list of mods.

Can anyone share their experience w/ the EVS mod on a Pioneer?
I'm thinking of a modified DV47A & thought that Modwright was the place to go. Then discovered this EVS place where the mods seem to be more extensive (& hence have a potential to make the DV47A sound much better??? Might be an incorrect assumption!). TIA

Dan:

It may not bother you, but the DV45a and the DV47a and the DV47ai all have a decoder that does, in fact, have the chroma bug. It is not something that is in some units and not others. Also, it is not subtle...these players all have a bad case of it.
The MPEG decoders that were used in these units all have the problem. Here's a list of the players that have chroma bug:

As more of an audiophile than videophile, I never thought my DV47a had the chroma bug, basically that was because I really didn't understand exactly what it was or what I was looking for. Once I read this:

http://www.hometheaterhifi.com/volume_8_2/dvd-benchmark-special-report-chroma-bug-4-2001.html

and put the Toy Story menus up with my DV47a...it became very clear to me. Of note, is that the chroma bug problem affects other aspects of the video experience.

Once you know what it is....it "bugs" some people. Ignorance of this issue, for me, was "bliss" because once i understood what I was looking at, I started seeing it all the time.......and I then needed to retire the DV47a for video. I picked up a Denon with a decoder that doesn't have the problem.

I still love my Modwright modified DV47a for SACD only.

Harry- Apreciate the info on the bug.I got the Pioneer to use as a player/transport. It's never been hooked to a monitor. I'm surprised Pioneer hasn't issued a recall to
fix the problem.

Aloha,

Dan:
Because the chroma bug problem is in a number of the mass produced decoders, Pioneer would have to recall virtually every unit they put out for several years. And because most people don't know about the problem or what to look for....most people don't care (even though they should). What surprises me...is that many new units from multiple manufactures are still released with the problem.
