Don't get me wrong, I wasn't putting Videobox down because it looks great but I did not see a Download Full Movie option on the site, only streaming.
It does allow you to download Full Scenes but it doesn't appear to let you download Full movies. And the only 2 formats I saw for downloading is MP4's:
H.264 640x480
Iphone 320x240
I looked at several titles on the site, most notably these movies below from their front page and only 2 MP4 formats are available for download.

And I saw a Play Movie link for each movie but I didn't see a Download Movie link unless I missed it
