No Not at all.
Sure you caould have the set up described.  With a splitter out on the
video cable so that it hooked up to both the MicroTV and a monitor
you could indeed se what you were doing in a window.  Make for some interesting
recursive stuff tooo...

As far as slowing the machine down...  MicroTV does slow the mac down a bit
but I think that 30% may be a bit excessive.  As far as the NTSC code
slowing the mac down 50% NO WAY!  I wrote an init to do that 18 months
ago and there was no apparent slowdown at all.  Why should there be?

All the init does is change some of the hardware registers in the card
changing what it displays, the mac should not change speed at all!

Regards

PS. I would really like to see myself in a window!
