Those with a PC next to their Amiga might want to consider
using a TV-tuner card as a way to get the Amiga's video onto
the VGA monitor.
I have an RGB->S-video converter and the output goes to an
older TV-tuner card (BT-848 chipset). Not only does it
de-interlace but has the added bonus of letting me stretch
the screen out to about 710x480 which is outside the visible
area on some 15KHz TVs/monitors. The disadvantage is that
PAL screen modes have no color. Also, the full 1280
resolution can't be displayed.
