Hi.
This is a question for anyone who knows about TV and VCR standards.

First, a story:

A friend of mine in Germany has sent me couple of video cassettes
with movies that he recorded over there with (I think) PAL standard.
When played on our NTSC VCRs, there is nothing but snow on the tube
and sound is completely garbled.  Then I sent him couple of tapes
I bought locally.  He recorded couple of movies on his machine, but
when he played the cassettes back he got nothing but snow on the screen
and garbled sound.  Then he sent the cassettes back to me.  When I
play them on my vcr then sound comes out ok except it is a little faster
(I guess maybe tape transport speed difference - Is it AC freq dependent?)
and I could see the picture except that it was vertically unstable.
So, I got myself an old tv and changed the vertical hold capacitor.
Now I have it stable but like I said it is a little faster than normal.

Now the question is,  are the VCR tapes made for USA different from
the ones made for Europe???  Would it be too hard to create a translator
that would go between an European and an American VCR, probably at the
composite video/audio level???

Thanks in advance for any information!
