Keith: It all depends on what is on the card and how much space you have available. A 1 gig card would have tons of time on it. However, the real problem is going to be that you will not be able to edit that recording on the Book Port, so I can't imagine you'd really wanna do this--not to mention the poor recording quality. However, you'll get several hours, provided your batteries don't run out. Also, keep in mind that we have not really tested it that way, so you're on your own there.

Apparently, I wasn't on the list. So, I'm going to ask the question again. I apologise to the list for the repost. I have a bookport with a 1 gig mem card in it. If the card is blank, how much recording time will I have with a 1 gig card? Thanks Keith
