I recently hooked up a VCR (actually an 8mm CamCoder) to a ND to tape
a Mathematica animation from the screen. This turned out to be very easy
using ScreenScape. The quality of the video was okay, but I had a couple
of questions that I was hoping I could get help on to improve the quality.

1) The main problem with the video was a low-key jitter. The jumping wasn't
bad but was noticable. Anyway I can eliminate or redued this?

2) Any tricks to reduce the "moire pattern" effects? (I know, don't wear
a cheap suit, right;-)

Thanks in advance,

Charlie

Unfortunately I can't help here; I just want to piggyback on the  
question. We got our ND recently and haven't used any of its special  
capabilities yet; where is the documentation for NeXTtv, ScrenScape,  
and VideoApp? Where is the documentation on hooking the ND board up to  
video input and output? (Maybe there isn't any and I'm just supposed to  
intuit all this?)
