allow average breaking computer digital-delivery down download files gig home item lecture load music parts paypal personally preferably range recommend sell site size smaller video web writing

I saw your web site at Paypal. One question. I am writing a lecture that I am going to sell through digital delivery. I am afraid it will be too large to download for the average home's computer. What size would you recommend/suggest such an item should preferably keep below to allow the average computer to down load it? Right now my lecture, with music etc., is in the 1 - 1.5 gig range, but, I can make is smaller if I really need to.

People do sell files of that size but I personally will recommend breaking up the video in 4 parts so it's easier to download.
