I'm saying you might get better results if you had a TV card to
capture the output directly from the S-VHS coming from the camera.
The only other option is to head to windows media encoder, go to the
Properties button (cancel any wizard just before it starts) then go to
the "Video Size" tab.
On there, select Cropping dropdown - Custom, and set the cropping size
to let's say 4 pixels top/bottom/left/right
From your screenshot it looks like most of the edge artefacts are onthe left and right, so try a few seconds encoding with it cropped,
play the encoded file back to check it, then rinse and repeat with
more cropping till the interference bars go away.
Try to stick to multiples of 4 for the cropping (the codec prefers
that and may even barf on odd-number crop differences)

the set top DVD recorder and record them from the VCR to the Set Top DVD
recorder. I then take the DVD out of the set top DVD recorded and insert it
into the multimedia drive on my computer and open any one of the video
editing softwares on the computer and import the VOB files that way.
Nothing to connect. It's only when I either try to play the DVD's directly
from the multimedia drive on my computer or the imported VOB files that
there is the dodgey distortion on the edges. If I play the DVD in the set
top DVD recorder I recorded them in they play perfectly fine.
With reqard to your suggestion about the TV Tuner Card, there is already a
USB version available that's made in China by EasyCap and it's a piece of
garbage. Roxio makes one that they have recently offered for $30 and I may
try that one since it offers the options to plug anything into it.
Thank you again for your reply...

Sessons Greetings All-
Suddenly for some reason whenever I import video to my computer there is
now
distortion on the right and bottom borders of the captured video (see link
for example):
http://www.box.net/shared/dgs4utck4f
That looks like problems with an Analogue Capture card/device
I am copying old VHS-C type tapes to DVD and importating the video footage
from the DVD's with my DVD drive in my computer.
So if you connect the VHS player to an Analogue PC TV card, and record
from that to an intermediate file - do you still get the analog edge
distortions ?
Analogue VHS is generally a bit iffy round the edges.
On TV playback, the TV will overscan the image (effectively cropping
off the dodgy edge bits) but a DVD recorder would capture the complete
frame including the iffy bits.
When I play the DVD's back in the player they were copied with they play
perfectly fine, but when I play the DVD in my computer there is the same
distortion, even after the captured video has been written to my hard
drive.
You mean play the DVD back on a *TV* - what happens if you playback on
a PC in (say) media player - set the player border colour to something
other than black - cyan or pink - to see the edge interference.
This has now happend in the past, it has only recently started to happen
as
I have used this method of transferring vdieo to my computer in the past
without error. As a matter of fact, the videos that I have captured in
the
past using the very same method are no too also playing back with
distortion. It would almost seem that something is interferring with it
and
I just am not able to figure out what's going on...
Could anyone help?
My operating system is Window's XP Media Center Edition with Service Pack
2
updated and I am using either the ULead Video VideoStudio SE or ArcSoft
Showbiz DVD2 or Roxio Creator 2009 or Windows Movie Maker and the same
thing
is happening with either.
If you have an analogue TV card already, try capturing using that,
direct to the PC. A new Analog TV card should be very cheap now, as I
imagine manfacturers want to get rid of the stock as most of the world
moves to digital-only TV broadcast, so it's a good time to buy one.
Something like this http://www.ebuyer.com/product/160946 might well be
good enough for occasional use if you wanted to record direct to the
PC
You should check the camera, but usually it's possible to find or buy
a cable to go from the camera to the composite TV input on the TV
card.
