	Last week I posted a question concerning RF Modulators and 
their necessity in recording Amiga video output to a VCR. I got one
response asking why one was needed and why I couldn't just take the 
Amiga output straight to a VCR. Well, I just purchased a copy of 
the SEPT/OCT issue of INFO magazine. In it there is a review of much
of the Hardware needed for video work. 
	First, let me state that my terminology was INCORRECT. An RF
modulator is not required to get Amiga video to a VCR, a "VIDEO
ENCODER" is. This device creates composite NTSC video from the RGB 
analog (non-composite) signal of the Amy. (This info is from the INFO
article)

	QUESTION(s) ONE: I thought that, since we have interlace, it
		         WAS NTSC!! Is the problem that I need to 
		         convert from non-composite to composite??
		         What does this mean???

	It also states that SOME of these encoders also provide an RF
signal for a TV output. (thus RF Modulator). 



	QUESTION(s) TWO: I purchased a CMI Video encoder for my Amy. 
			 INFO rates this as the best available encoder
			 that they actually tested. However, they state
			 that there is a CMI VI-500 and a VI-2000.
			 I have used mine somewhat and gotten reasonable
			 results (except for bursts of what appears to
			 be RF noise when I start recording), so I never
			 looked closely at the box. I just did last 
			 night and I have the CMI VI-500!!! But I have
			 been using it on my Amy 2000.

			 CAN SOMEONE TELL ME THE DIFFERENCE BETWEEN THE
			 VI-500 AND VI-2000? Do I need the 2000 version?
			 The place where I purchased it has closed. Can
			 anyone affiliated with CMI (or anyone who plays
			 one on TV ;^)) tell me the difference and if
			 I can send in my VI-500 with the original box
			 and trade it in for a VI-2000?



	If no one from CMI is on the net, does anyone out there know how
I can get in touch with them? 


Thanks,
