Completely lost between S3 and EasyVideoPlayer...

So I'm at the stage where I'm about doing okay online, know my conversions roughly, and am about to scale up using paid advertising. I pretty much use video for all my content and up until now have been using screencast to host those videos which for the most part has been okay, but it's a real pain when my bandwidth limit gets reached (occasionally videos buffer slowly as well).

Looking to scale up, I can't have bandwidth limits affecting me and so I just got my amazon S3 account, my cloudfront account, and my Easy Video Player account, and have landed myself in a spot where for the last four hours I've just been overwhelmed technically and have no idea what I'm doing. And so I'd really love a bit of help here (although this post is quite long so if you don't care to help, totally understandable!). Here are a few of the specifics...

1) I'm not sure where to load my videos up to? Do I stick them into my S3 account using the firefox plugin (which I have), or do I upload them to EasyVideoPlayer directly?

2) I can't seem to make my videos (in my S3 account) readable. I found a tutorial online and it said to just right-click the file once it's uploaded and "edit ACL" to make it readable, but when I click "Edit ACL", nothing happens.

3) I have distribution channels set up (one by me and one by EasyVideoPlayer) but when I try to select a file in my S3 account to be distributed through either of those channels, it tells me I have no channels set up.

4) I've just edited a video in EasyVideoPlayer and when I click to see it play, it doesn't play.

5) I've found other sites showing how good Amazon cloudfront is supposed to be, and the video they used in their post as an example doesn't really play very well either. Starting to make me wonder a couple things...

Is this Amazon stuff all it's built up to be? And what's the difference between a video that streams and a video that buffers? 'Cause I think I prefer seeing the buffer line move up so I know exactly how much has indeed become watchable, but I'd certainly like to see that line move faster (so far the fastest buffering I've seen to date is with a pro account at Kajabi, but really have no idea why).

Whew, if you made it this far, awesome and thanks. I really don't expect anyone to go out of their way for me, but if you're sitting there bored and have some input, I'd love to hear it!

Cheers,

Rob...
