IMHO, without a doubt! I figure that if you can't tell the difference between
240 lines and 380 lines, you need to have your eyes checked. But then again,
the local TV columnist ran a list of VCR hints yesterday that included always
recording at EP since he claims that there is no difference in picture quality.
I don't imagine he's going to be a customer for SVHS. But I find the difference
between VHS SP and SVHS EP much greater than between VHS EP and SP. It's good
enough that I normally record most stuff at EP on my SVHS machine.

As to the TV with an S-Video connector, probably not of great value. Most of
the signals start out composite, so the S-Video buys you very little. I use
both and see little to no difference. If you have an SVHS camera, this may not
be true, but I don't.
 
> 2.  What are the major difference(s) between VHS and SVHS tapes?  

About $5.

Seriously, SVHS tapes have better bandwidth capability. My experiments showed
that you could record SVHS on a high quality VHS cassette at SP with fair
results, but at EP you could forget it.

Physically, an SVHS tape has a small hole in the bottom used by the VCR to tell
that it's an SVHS tape.

See above.

If you pay more than $8 for an ST-120 tape, you are paying too much. The
markups on SVHS tapes are often HUGE!

There are (at least) some Macrovision killers which strip off the sync

The 2 year application period is exclusively for existing broadcasters,
after that period each market will be opened up to competitors, if an
existing broadcaster doesn't apply and build a HDTV facility they will
lose their frequency allocation and licence when a HDTV competitor
comes along.  I think the broadcasters will be dragged along kicking
and screaming into the HDTV world just to keep in business whether or
not they want it.

 Well, don't ever plan on watching television in europe then, because every network

The Operations Manual (not the Owner's Manual) for my old SLHF-750 SuperBeta
machine gives a cartoon of two frequency response plots of the electronics;
the one representing EDIT in gives a slightly higher reach in frequency at
a cost of some S/N over the mid frequencies where the response seems to be
higher than average.  The manual for my Proton 625 eluded to some video
noise reduction applied to the fixed outputs.  The manuals for the
SLV-585/686 did not say anything about it, but the drawings seem to indicate
another form of noise reduction.  The effects are difficult to detect;
they all look like some kind of comb filtering applied to the video signal.
But all the manuals warn that even when duping tapes with the EDIT switch
on, some loss of quality will occur (as you would expect).

Hope this helps.

1.  Will recording an NTSC program on a SVHS tape on a SVHS machine yield 
a better picture (resolution) than a VHS tape on a VHS machine? 
If so, is it worth the extra $$$ (not counting the need for a monitor w/ 
S-video input)?

2.  What are the major difference(s) between VHS and SVHS tapes?  

3.  Can you fool the SVHS machine by inserting a VHS tape (with a hole

What about the resultant picture quality?

What is a good wide angle adapter lens for this camera?  Sony makes
a few - one with a 37mm attachment diameter, another with a 46mm dia
(uses step up ring).  There may also be aftermarket units.  I'd apprieciate
recommendations and guidance.  I am concerned about optical quality.
 Since the TR-81 is hi8, I want adapter to maintain the resolution of
the image.

I will post a summary of response.  Thanks in advance.

	The Fox station is the only station in the metro NYC

All this talk on rec.satellite on SVHS vs composite video is
confusing to me. Its important to me in that Im still trying
to figure out which IRD to buy...one with the SVHS or w/o.
There is only one IRD with this feature however.

The consenus I believe that SVHS from satellite is just composite
video so stnrd SVHS connect would yield no gain....unlike an LD
player. What am I missing here?

Would the purchase of the SVHS output IRD be for nought?

.I own a Sony GV-8 which is the type of unit you refer to (the Sony models are

There can be a real interference problem with some equipment.  The biggest
potential culprits are devices with RF recievers such as AM, FM, and TV 
tuners.  You will see the RF problem by holding a radio near the antenna
input on a TV.  There will be cross hatch interferencs on the picture.
If this were to happen to an important flight instrument, such as the new
satellite positioning system there could be a flight path error.  Even 
computers and video players/recorders without tuners can cause considerable
RF.  These units have very high frequency leakage which can also cause
problems with plane instruments.  The RF interference problem is real.  I
always ask the flight steward if its OK to use my palmcorder, and then keep
it to a minium.  Continental and Alitalia said yes.  I have not tried
American.  The new equipment (non-tuners) may have the proper RF shielding
in place, but I'd hate to be on a plane where everybody was operating 
equipment on board that could effect the navigation system and increase the
risk of an accident.

My understanding is that the deck(s) need to have some sort of speed
adjustment in order to properly synch the A roll to the B for A/B roll
edits. The AG-1960 lacks any sort of adjustment of this type, so there's
no way to synchronize the two decks so that they both start their
retrace at the same time. Result: glitchy edits when you try to do A/B
rolls.

Right? Does a TBC compensate for the lack of synchronicity? If so, then
you can add time code and use two 1960s as an A/B roll setup (assuming
you have an edit controller capable of doing it).

I've been wondering about this. I have a Sony TR705E (European version
of the TR81) and a Philips (sp?) LC2000 PAL/SECAM LCD TV with AV input
that I use as a monitor with my TR. Does anyone know what airlines
would have problems with my using this equipment on board? (I'm most
interested in European airlines, as, despite the address from which
I am sending this message, I am in Switzerland.)

Also, a question about the LC2000. In the user manual there is a reference
to a rechargeable battery pack made for this unit. To charge it, you place
it in the TV (it fits into the battery compartment),
plug the TV in, and leave it turned off for X hours. Well, does anyone know
if I could substitute this pack for regular NiCads and charge them in the TV
in the same way?

Hi All.

Last night while watching Star Trek The Next Generation (Broadcast in Stereo)
and using my Pro-Logic Surround system to maximize my viewing pleasure, I began
to notice that some of the voices in the center channel were popping in and out
of the rear surround channel.  Has anyone ever experienced this?

Being fairly new to Pro-Logic Surround, some of the possible explanations that
came to mind were:

  - My system is in need of repair (JVC rx805v)
  - My system was poorly designed (electronics that seperate the channels)
  - The Stereo TV signal was weak or in some way interfered with (Although
    the transmission was via cable and seemed clear)
  - The soundtrack does not lend itself well to surround sound.  There is a
    constant low sound (of the Enterprise Engines, I assume) during all shots
    inside the Enterprise coming from the rear channel - maybe the Pro-Logic
    decoder got confused and couldn't properly seperate the sounds.

Anyone else have similar experiences and/or explanations?

Thanks in advance,
