Asking lots of questions which I have been asking.

We are already starting to see second generation dye technology in the blank
CDs.  The first generation was rated at about 10 years.  DIC is claiming that
their new dye is good for in excess of 80 years (but they also said that they
had not completed their advanced aging tests and expect it to be good for 
more than 100).  What the sales droid didn't say was (but I am fairly certain
about is) this assumes storage in a dark cool place.  The sales droid guessed
the life of one of his CDs stored on the dashboard of my car to be a few years.

I would like to see more documentation about these accelerated aging tests
before I would trust the marketing department claims.

P.S. Keep asking these questions of the marketing types you run into.

After more experimenting and discussion with Greg, I've come to the 
realization that my original test was flawed and that the most reasonable
conclusion is that the A/D->D/A converters are being by-passed when the
Sony TA-E2000ESD "Source Direct" switch is on.  A schematic would eliminate
any doubt.

Subject: Memorex 8mm VCR with Audio & Video Dubbing
Organization: AT&T
Date: Fri, 22 Jan 1993 15:55:52 GMT

In the VCR/Stereo Buyer's Guide (from Video Magazine), there is
a short description of the Memorex 16-654 8mm VCR as follows:
Hi-Fi stereo sound; frame advance; freeze frame; forward/reverse
scan; audio dubbing; video dubbing; flying erase head. -- $500

I am mainly interested in how the audio dubbing and video dubbing 
features work.  Would I be able to first record the audio (in PCM 
stereo?), then record the video without affecting the audio, and 
vice versa?  Does it also have AFM stereo?  Does it have any
editing interface, such as Control-L?

I would like to know if anyone had any experience with this product,
the customer information number for the Memorex company, and/or
any dealers (local or mail-order) that carry this product.  

Thanks in advance for any information or suggestion.

I hope that this posting is in the right group. I'm 
just a beginner at this stuff, so I don't know
what I'm doing.

I have a uppper mid-range audio-video system.  
My problem is that I cannot figure out an appropriate 
way to set up my REAR SPEAKERS.  I've looked at all the setups
reccommended in the manuals, but they wouldn't work right
in the room I have.  Since the sofa is against the wall,
I can't put the rear speakers behind it.  Below is a 
rough description of the room.

Now due to family constraints (ie opinion), I cannot move the TV.
Also note that the sofa cannot get any closer to the TV (not too
good for the eyes). Notice that the doors also cause problems.  

Where would you put the rear speakers???

I think you might indeed be wrong.  On my TA-E2000ESD, which I tested
yesterday, I was unable to produce digital clipping in source-direct
mode, even when I was well beyond the point of digital clipping when
I turned source-direct off.  The OVER indicator lit, but there was
still no digital clipping (it's almost impossible to miss digital
clipping when it occurs).  The OVER indicator can even light with a 
*digital* source if you turn the digital input level up too high, which 
shows that the indicator by itself doesn't imply that digital clipping 
is taking place.

Pretty sure the 605 can not do CLV effects..  As far as I know, the

Yes.  But you usually have to drill or melt using a solder gun (better)
the hole that SVHS VCRs and camcorders look for to sense an SVHS tape
(unless you modify the electronic circuitry in your VCR to override the
SVHS hole "sense" and allow you to record SVHS on any tape VHS or SVHS).

People have reported on the net that if you use a reasonable good
quality VHS cassette ( Sony ES, Fuji A/V Pro, etc.) you can get
a reasonable SVHS recording on it (with a little bit more noise)
but that EP (aka SLP) SVHS recording on VHS tapes suffers considerably.

SVHS tapes do have different formulations than VHS tapes (higher bias?)
since they do have to record a wider/higher bandwidth video signal.
Standard disclaimer : there is no guaruntee that VHS tapes will work
well for you if they are used for SVHS recording.

Here are the resolutions (figures for s/n and other metrics have been
published in the recently resurrected VIDEO REVIEW mag - once in the

        SVHS            400-425
        Standard US TV  350
        Broadcast NTSC  330
        VHS(SP)         240-250
        VHS(EP)         220

SVHS EP mode would be somewhere between VHS(SP) and SVHS(SP).
If it were good (good tape, good VCR, good source material) I
would expect it to be between 330 - 400 lines horiz. res.

I agree with this conclusion completely.  Go for the E200 if you have a good
amp system; if not, get the RX-V850, or better still, the RX-V1050.

I remember when I bought my DSP-E300 (a slightly better model with 8 more
DSP ambience modes: Pavilion, Church, Hall 1, Hall 2, Jazz, Disco, Movie 1,
Movie 2) in 1990, the salesman was pressuring me to buy the DSP-A700/AV-700
combo instead of the E300 because, as he said, the -700- combo provides
more oomph & lots more bells and whistles.  I told him that I already have
a very good a/v amp (Yamaha AV75 PRO) and I was not planning to give it an
early retirement just yet (my AV75 PRO was only a year old at the time).

Anyway, he backed off.  Me, I'm still a very satisfied E300 user.

Still, doing it by turning the input level to max on normal material (as
opposed to test tones) works just fine (if you have a CD player with peak    
search, that's a good way to find a sufficiently-high-level signal to 
use).  There may be analog distortion induced by using the maximum input
level in source-direct mode, but it's pretty easy to distinguish this from
the digital clipping that occurs when source-direct is off (which sounds  
like very short bursts of static).

The analog distortion explains why there's a digital input level control
and why the OVER indicator can light even with a digital source.

 CD-G uses data area left on normal CD, and contains graphics

 CD-G Karaoke player can show picture and lerics: it has video

Is this distortion present in the XBR^2 sets?
One of my rationales for buying the XBR^2 instead of an 
equivalently priced 35" set was the better geometric
performance (supposedly) of the smaller sets. 
Video magazine did a review of several 35" sets recently,
and noted the excessive geometric distortion of the 35" sets
in comparison to the 32" models.

>(And btw, Sony fans, I've seen Zenith 27" sets without this problem -- so it's 
>NOT inherent in the screen size.)

Are there any 32"-35" sets with better performance in this area?

This is in response to the anger that has been vented against Sony for their 
tv sets especially the XBR series. I can understand the outrage when 
something is bought and doesn't work to specifications and when customer 
service and repair are not obliging. I don't quite understand understand a 
couple of things however and it may be because I haven't followed the thread 
from the beginning. Apparently Mr. Ricciardi had a problem with geometric 
distortion on his set (as do others) and have felt obligated to either 
attempt adjustment themselves or have called their sets in for service. From 
what I understand, the techs either can't or won't "fix" them and fixing the 
sets themselves is not working. 

 Did the sets in the showroom exhibet this problem? If so, why did these 
individuals buy them? If they didn't, than thats a different story.

From my own experience, I've owned Sony tv sets now including my current 27" 
XBR for fifteen years now. I have never experienced a problem and absolutely 
love the picture. I personally know four people with 27" Sonys (XBR and 
Trinitron sets) that have no problems whatsoever with either reliability or 
geometric distortion. I would wholeheartedly purchase another Sony tv set in 
the future.

I just wanted to place a different viewpoint onto the net so that people 
don't think that Sony XBRs are total garbage to be avoided. I'm a happy owner 
along with four of my friends.

I hope the people who are having problems that are legitimate will acquire 
satisfation. Please keep us posted.
