OK IMO if you discover new facts or find the answer ...

I wondered if there was any advantage in feeding a bT878 card from
a PAL camera as against an NTSC one when using Vic.
The data sheet for the Sony EVI-D100/D100P says 768 x 494 effective 
pixels for NTSC and 752 x 582 for PAL.

Probably more trouble than it's worth for us here in North America
