DVD/VCR Recorder - Green colour cast
Terry Pinnell
our old VHS tapes copied to DVD. My existing setup is Panasonic
TX-32LXD52 32" LCD TV, Philips DVD757VR combo, Sky+ box (i.e. no DVD
record facility).
I've got it working after a fashion by simply removing the SCART and
RF lead connections from the Philips and connecting them instead to
the Bush. But when I play either a DVD or VHS, the picture has a
bright green overcast.
HOWEVER ... I thought I'd try the Copy VCR to DVD operation anyway,
and was surprised to find it worked OK. When I played the resultant
DVD on my PC, it looked and sounded fine.
Can any of the technical experts suggest the likely cause & cure
please?
On a different point: the Bush accepts only DVD+R and DVD+RW types.
The first fresh DVD+RW I tried was rejected as the wrong type. I tried
another DVD+RW, a different brand but already used previously, and
that was accepted. Are you supposed to format discs before use? Or is
the Bush probably just fussy about brands?

Most likely would be one of the Scart connectors is not seated properly.

Thanks both, but naturally I ensured they were OK, just as they have
been for the last year or so.
I managed to reach Bush/Alba technical support and the prompt
diagnosis I received was similar: "Faulty SCART cable." Although I
didn't see how that could possibly be the case (for the reason I've
just given, namely a long period trouble-free use, with DVD and VCR
signals), I did change it for another - with the same green result.
Yet, given that the copying is OK, which doesn't *use* the SCART, I
can therefore only guess that it could be the SCART socket (or
associated components) on the Bush. Does that sound reasonable please?
Or could it be anything to do with the fact that the SCART cable goes
to (or comes from!) the Sky+ box? Maybe that's fine for the Philips
but not for the Bush?
Java Jive
using the Bush's internal DVD-R, which I presume because you say that
you've unplugged your Philips DVD-R, it shows no problem.
I'm not clear from your description whether the connection path
between the Bush and the TV goes through the Sky STB. Presumably and
hopefully not, but if so the first thing is to try connecting the Bush
directly to the TV.
My best guess is that the Bush is outputting either Component Video or
RGB Sync On Green, and the TV is not configured to/cannot accept that.
Check in the menus of both devices that they are both set to send and
receive the same type of signal: either both RGB, or both Component.
If you then still get the problem, most likely the Bush is sending
RGBSoG, which the TV doesn't understand, and you'd then have to
configure both to use inferior Composite Video instead.

will display an image with an extreme green tint, if any image at all,
when given a SoG input."

Known problem with Panasonic tellies (which I also have).
Your VCR is outputting RGB with sync-on-green. This confuses the colour
balance circuits in the TV resulting in a bright green display. I had the
same problem with a Hauppauge MVP, the fix was to switch the MVP into
S-video mode. Alternatively it is possible to disconnect pin 16 in the
SCART cable to force the TV into using composite video, but there is a
loss of picture quality.

it would be entirely possible for a Bush, or even one of the bigger
names, to have this kind of fault.
You should check that the scart is using the RGB out socket on the
Bush and RGB in on the tv.
Java Jive
this problem, so my contribution was just a good guess.
Perhaps to avoid hacking his cables around, the OP can use Composite
Video In on SCART AV2, if his model has this connection - the
smaller of mine doesn't, the larger does.

Thanks both, pleased to find the answer to this puzzle.
I'll live with it for the duration of this loan, as it's not affecting
the copying itself.

This is the first time I've done any VCR to DVD copying and so the
first time I've encountered the issue of the short duration capacity
of a DVD using standard quality. Disappointing! Particularly because
for many of my VHS recordings I didn't note their length, so have to
guess whether to use SP or EP (lower quality).

Thanks Alan. I did indeed manage to connect it without disconnecting
existing stuff, with a Scart from AV4 on the TV to the Bush. And,
although I could swear I'd tried this before without success, when I
experimentally switched that from AV4 to AV2 I was surprised but
pleased to see the green cast had gone!
Have now managed to do all the VHS -> DVD copying I want for time
being. It proved fraught with various other quirks, including disc
errors ('cyclic redundancy checks', whatever they are) which prevented
my copying the DVD to my HD for editing. (Yet in some cases I could do
so using editing software such as VideoRedo, which is apparently more
tolerant of such errors than Windows Explorer.)
And the latest problem to baffle me was that I was unable to access
the full Bush DVD Menu, to use Erase on some already-written DVD+RW
discs. Yet I *had* done so the day before!
