Unless you are using high quality video recorders (SVHS, Hi-8 or higher,
certainly NOT VHS) don't even think about dubbing the anaglyph segments to 
another tape...

The way in which colour is encoded on an NTSC signal (or PAL for that 
matter) means that generation loss (dubbing from tape to tape) very
quickly corrupts the colour content of the signal.  

Anaglyph video colour is very quickly affected by generation loss.

So if you are serious about keeping these segments (and wanting to watch
them in 3D), don't dub them to another tape (the loss in quality may
render the anaglyph 3D unviewable).
