Who did you talk to at Commodore to get this 'line' on this problem?

None of these folks work for Commodore. ;-)

Well I grant that this could be a possibility.  We have installed a 
Magni genlock in a 3000 and have not had any problems.  Perhaps there
are exceptions to this "rule".

Not true.  See above.

This quote is the whole reason I decided to post on this message.  Please
don't post what you "understand", especially when it is to the determent
of the Amiga.   Perhaps you should say which version of 2.0 you saw this
on?  I have been using a A3000 with 5 meg for all of my AmigaVision 
development under 36.68 /ks 36.143 and though there are problems with this
version -- it does NOT guru when you open a HIRES/OVERSCAN screen.

Perhaps you should :-)
