Radeon VIVO/AIW Capture - newer cards better ?

J

jon

I have an AIW 7200.
I have many times attempted to capture VHS VCR recordings for ultimate
archive to DVD.
The problem that i have is that, despite the recordings being from
terrestrial broadcasts and hence having no Macrovision present, the AIW has
always
kicked in its copy-protection ( flash bright / dim etc etc ) and hence i
have been unable
to use this card for VHS video capture, which is why it was bought :(
(This on different recordings on different VHS decks, both rec and pb)

So, before i buy a newer ATI AIW or VIVO, does anyone know if the newer
cards are
less fussy ( macrovision wise ) than the older generation , or am i wasting
my time and
money getting a newer one on the vain hope that they will work as required ?

TIA

You may need to be a bit more specific about what VCR tapes you are trying
to capture.

Using a 9000PRO AIW 3.10 Cat drivers, I find most commercial tapes won't
capture, all home recordings (off-air, camcorder) are just fine.

Hi
Thanks for the info.
The problem i have is with "off-air" recordings made on VHS decks, in both
standard VHS and
S-VHS modes.
I appreciate that commercial tapes are Macrovision encoded, and as such i
would
expect the copy-protection to kick in on these.
What i cannot understand is why my AIW card seems to think that off-air
recordings, played
back via Composite or SVHS inputs, are macrovision encoded.
AFAIK thats impossible as a VHS deck wont "record" a macrovision encoded
source, and as such
its impossible for the VHS deck to introduce sync corruption ( i.e.
Macrovision) into playback of "off-air"
recordings.

It seeems to me that my old 7200 AIW is VERY touchy about the sync pulse ,
and incorrectly
assumes a non perfect sync == Macrovision encoding.

I was just wondering if the newer cards are less touchy than the old 7200

Sorry - you did clearly say "terrestrial broadcasts". But even so, the
situation seems to be that we don't decide what is Macrovision protected,
ATI's driver does.
I suspect there are a lot more variables than the age of the card - you
could probably buy all new hardware and then find it was a connecting cable,
or, interference from a fridge, causing the trouble.

So - 9000 PRO, Cat3.10, W98SE, on Abit KX7333, using VIA 4.38, in the UK
(etc etc etc) works fine!

I have swapped vhs decks, leads etc. & also tried all releases of ATI
drivers (and hacks)
all to no avail.
Anyways, thanks for the info ...

I wonder if one of those video cleaner-upper boxes (which also remove
macrovision) would help.

Maplins http://www.maplin.co.uk/ call it a "Copy enhancer". It did nothing
for me re macrovision, but it may well solve these problems.

I have been using my 7500 for all types of VHS-HI-8 recording. My
brother has a 7200,
he has no problems your describing, in so far as, thinking all tapes
are protected.
I have seen leads and certain VHS players that caused the 'positive'
detection.
One such circumstance required us to 'ground' the VHS to the computer
tower.
That was strange as the power strip handled all the power grounds.(and
through coax)
Length of lead. Type also, what is it RJ56 ?GR8? I always twist these
around and get them wrong
senility, anyway the newer 'digital' coax was a problem when used on
his 7200.

Good thought about grounding - i will experiment - nothing to loose :)
The interface leads are all Composite Video ( scart / euro-av) or SVHS.
I did try RF/Coax but that didn't help.
Thanks for the thought ...

There are better ones whichm do remove macrovision.

There was even an article in Elektor magazine Jul/Aug 2002 on how to
build one.

How can he be any more specific? He said they were over the air broadcasts
recorded from TV and hence shouldnt have macrovision present.

Yes, I realised that which is why I reposted.
But it seems to me that some people have more problems than others, so
thinking that the ATI macrovision detector 'kicks in' for reasons other than
the type of source.

Me, I've tried DisableATIMacrovisionDetection (several times) with no
success at all, yet it clearly works for others. Now here's someone who even
has problems with off-air recordings - there is something else going on
here.

Yes, I seem to recall at one time there were issues with Macrovision
protection being triggered by video without Macrovision on Ati cards.
Doesn't seem to have come up for a while, though.

AIR it was triggered by video being too bright, too dark, or rapidly
changing between bright and dark. Possibly searching the Rage3D forum might
come up with something.

I tried doing a vhs capture the other day and got this problem. I
don't know if it was Macrovision though. It was a quitre old tape and
changes in scene caused the brightness to go really high.

I'd like to know if it can be stablised though. Some sort of
brightness lock would seem appropriate.

It's not a problem I've ever encountered, myself. I simply recall that it
used to be a quite frequently mentioned problem at one time. As I said, try
searching the Rage3D forum - at http://www.rage3d.com/board/.
