While I haven't seen this hack work, we have the same problems when we try
to output NTSC video with our NuVista 2M board (overlaying video an
graphics on the monitor is no problem - it is the NTSC [TV] output which
flickers and loses the edges).  It is my understanding that this is a problem
with NTSC video's limited bandwidth.

Don't be surprised if the RasterOps board's output also loses the edges
and flickers.
