iMac USB question
Are each of the USB ports on the new iMacs on a separate bus or on the same bus? I'm asking because I want to have multiple streaming analog video from cable tv come into it. Right now, while using a MacBook Pro, there is not enough bandwidth to allow 2 streams at the same time. Apparently both USB ports are on the same bus. So I'd like to know if I get a new iMac, will it accept both sources of video. Would there be some other way to get both streams into the unit?
