I am ignorant about the iPad, but I have 5 movies (Holographic Universe Workshops) I want iPad owners to be able to stream and/or download and watch. I know they can't stream Flash files (which I currently offer on my website). So I have several questions.... 1. If I provide a .mp4 file on DropBox, for example, can someone stream that movie on an iPad simply by clicking on the DropBox link I give them? Do they need Air Video or StreamToMe or DropBox's iPad app in order to stream it? 2. If an iPad wants to download the movie to watch later (rather than streaming it), is the .avi file I offer sufficient, or do I also need to offer a separate .mp4 file for download as well? In other words, does this download .mp4 file have to be separate from the streaming mp4 link, or does the streaming file download automatically? 3. Just to make sure, I understand that .mp4 is currently the only file type I can offer (NOT .m4v, for example) that would eliminate the need for an iPad to make a conversion. True? Or am I making this way too complicated? I have an .avi file for download and a .flv file for streaming, and I want iPad owners to be able to stream and download these movies. What the best way? What do I have to do to make it as easy as possible? Thanks.
