[Leica] Photographing a video monitor

["Roy Zartarian" <royzart@connix.com>]

LUGs,

I'll be doing some shots where a video monitor is a significant part 
of the image. Because noise must be kept to a minimum, I'll use 
an M body.

What's the fastest shutter speed I can use with the focal plane 
shutter to prevent bands from appearing across the screen? I recall 
reading somewhere that 1/8th sec or slower is necessary but can't 
locate the information among my resources.

Thanks
Roy
