You have to switch, yes. Some cards do it quickly (like Meteor-II w/rapid channel switching DCFs, I hear), others not so quickly. You have to be able to disable automatic gain control or otherwise channel settling time will be intole- rable (that depends, of course.) Then again, if you use many cards with full frame rate, you gotta have a decent chipset or you'll get some "nice" artifacts in the grabbed feed. Jonk
