I have now almost fully configured my DVD/VHS/SAT TV & DV webcam feed to
work with WME9 (live broadcast) toWindows Media Player clients (File, Open
URL) via a dynamic dns -

http://adrian.dyndns.info:1219

One further query - why is it that I can broadcast some VHS videos but not
others? Most VHS seem to work - but one in particular (newer) won't display
video - even though audio comes through... Some kind of copy protection?

Any software (vs hardware) tricks on this? Yes, VCR/DVD/SAT/TV feeds are via
an analogue TV capture device - an oldish Hauppaguge WinTVUSB (USB 1.1)

Another good tip - tricky to work around though...

I'll alternate the VHS tapes every 10 minutes just to prove my point for the
next few hours ;-)

Actually there seems to be a bunch of newer VHS tapes that won't give
video...

I'll leave the older VHS stuff on until anyone taps in - then I'll flip
over...

It gives 404 to me... BTW, what you're doing can be useful to a lot more
people out there, I'd suggest you to write down every step and share them if
you want... I'd be glad to host it at www.wmwiki.com

It's not a website - that's why you will get a 404 when you try to open in
IE etc. Gladly share all I am doing with your guidance.

Macrovision does not scramble the signal. Basically it
inserts a high level signal into a non-viewed portion of the
video stream, and this would exploit the automatic gain
control on the recording device. The AGC circuit would think
the video was too bright and attenuate the signal to reduce
that artificially high level with a result of the actual
video signal being too weak to be visible.
Their are macrovision 'decoders' available that basically
clip the overpowered signals, or just passing the signal
through an old vcr may do the trick also- I found that out
using a high end sony vintage ~90.

Actually, I should be saying sorry, as I did not read your
entire post. The URL you posted in the part I did not read
appears to be a mirror of the resource I used to confirm
what I had thought was the way
