"From my browser I noticed if the download rate gets very slow at first, if I click the pause then continue controls, the rate then suddenly speeds up and the download finishes very quickly."
Thanks, but I've tried that trick and it just ends up with a server disconnect if I try it more than once. For me it's more of an Amazon problem. Every company that uses Amazon's servers, I have problems with download speeds and corruption problems. Like I say it's probably just where I live.
To be fair I just heard that Netflix was having download problems and they use Amazon's servers.
