Hi Bill,
Looks like you're going to have to look for another hosting provider. 1.5 Mb over an hour is plain ridiculous. DMX even goes out of its way to make the upload process as smooth and clear as possible (with progress bar). There is absolutely nothing that in some way piggybacks on the inbound traffic (i.e. there is nothing squatting your bandwidth) from the module's side. Either your up speed is too slow (I test this with
http://www.speedtest.net) or the hosting providers inbound speed is below par.
Their statement to 'use FTP' instead is somewhat puzzling. The bytestream may be marginally better, but not noticeable to you. FTP is by nature not a very secure protocol, so admin's usually advise to stay away from it.
Final note: you can of course upload using FTP and then import in DMX using the server path you uploaded to, but it is a cumbersome process. And for 1.5 Mb it's absurd. Have you tried the WebDAV connection?
