Default Sony DVD player update

I am finally able to see the replies to my post (posted twice because
I thought the first didn't make it). First, thankyou to all that
replied, especially about the usenet being screwed up. Now I know it's
not my account or computer. Anyway, yes, I had the DVD player
connected through my VCR. I bought an Orion TV a few years ago (yes,
it's a peice of garbage but it works), and it only has one set of RCA
inputs. Currently these are being used by my sattelite receiver. I
disconnected this and routed the DVD player straight to the TV as
suggested, and what do you know - it works perfectly. I don't quite
understand the macrovision issue being a cause to the problem. I could
somewhat understand the digital to analog having an effect. Well, I
must say I feel like an idiot for not even thinking about this as
being a cause. I had to look to see if this is how I hooked it up!
Thanks for the replies and as usual the problem was pointed out. Now I
like my Sony DVD player! Thankyou!

Buy a switchbox. They're cheap...or make one.

The MacroVision is an issue to stop you being able to analog-record a
commercial DVD onto a videotape, potentially making it a 'pirate' copy. It
inserts high level bursts of pulses onto the sync pulse porch level, which
most VCRs - the old Sony Betamax machines being a notable exception - use as
the reference level for the AGC clamp circuit. The bursts of pulses make the
average level shift, which in turn causes the AGC clamp level to shift,
which results in the cyclic brightness level shift that you see. As others
have commented, just get a manual or automatic scart multiplier box.

I hate macrovision. All it does is interfere with honest people who
actually bought the original DVD. It affects the sync on my video
projector which is only 3 or 4 years old. Can someone explain to me
why they insist on adding macrovision to the progressive scan output
of a DVD player? No VCR can record progressive scan video. It's
ironic that the best way to get around this problem is to make a copy
of the DVD.

Thankyou for the info. Now I understand why this was happening. But
pardon my ignorance, what is a "scart multiplier"?

Just a box that multiplies the number of scart connectors available to you.
A typical "cheap 'n' nasty" manual one might have two or three scart
connectors on the top of the box, a two or three way switch, and a short
flylead with a scart plug on the end. Fine for the occasional need to take
output from a source that's alternative to your 'normal' hook up. Better
ones make use of the scart switching signals, and can automatically route
the needed scart source to its output, with no intervention from you being
required.

This is a UK site, but it will show you the sort of stuff available, and you
should be able to get similar in the US. I'm pretty sure that I've even seen
them in Walmart when I've been there.

That is if one has SCART. It is rare for equipment in the US market, where
the OP is from, to have SCART.

SCART, for the edificatino of the OP, is a one connector and cable system
for interconnecting A/V devices, typicaly in Europe and other places PAL is
used. For some odd reason or another, it was never introuced into North
America.

Macrovision messes with the AGC of VCRs to prevent piracy, creating an
unwatchable copy.

Unfortunately, some VCRs have the AGC on the video input, rather than the
video record, which makes them not useable for RF modulators for DVD
players.

Yes, Gary - you're quite right now I come to think of it. It also gets known
as a Euro connector, which is of course a dead giveaway - although I'm sure
I have seen scart accessories in Walmart over there, but I could be wrong on
that point. Absolutely everything is connected that way here, and it's a
very convenient way of doing it, and works well once you get your head
around it. As well as the video and audio signals both ways being available
at the connector, there are also switching control lines, where devices in
the chain can control the signal paths between each other. So if you pop a
disc in your DVD and just hit play, it will inform the TV that it is looking
for access, and the TV will respond by automatically switching to the input
that the DVD is connected to, and so on. It's beginning to be superseded by
HDMI now, which I think is a bit more world wide.

You may have seen V-port, or some other game console specific connector.
The only Scart I've seen is in some imported DVB satellite receiver or
perhaps DVD palyers. Equipment mass manufactured for the US market just
doesn't have SCART installed. I have seen empty spots on boards for
SCART connectors though, in some gear.

Yes, HDMI is being incorporated into new digital sets and set top boxes.
