I think I can help a little here... or at least try.
The majority of what's already been said is very much true. There are certain file sharing websites (such as Rapidshare, Megaerotic, Mediafire, etc.) that only allow you to upload a certain amount of MB via a file. They differ from site to site. It would be easy to just pick certain sites, but then, there's a twist. If you're not a "Premium User" of certain places, then the
download speed is significantly slower and you're sitting there with your pants at your ankles waiting for that hot new clip to reach your hard drive and that is just bad.
When it comes to full movies, the smallest I've ever seen a DVD rip of a movie would be about 700MB (which is about an hour and 30 minutes; give or take a couple). Let's say you upload that to Megaupload. Downloads in about over an hour (if you have a high speed connection).
But then... that's it. You have to wait HOURS before downloading again from that site (unless you're me... there's a small way around that, but it's difficult to do).
With Rapidshare, you have to break it up into parts. The most you'll wait without a Premium Account is about 15 minutes per part. So... at most, you're looking at an hour again for a full movie download.
Sendspace sucks COMPLETELY. It's probably the most hated of the bunch and by the time the movie hits your hard drive, you're celebrating the New Year... of 2011. LOL
ZShare is OK, but they have massive pop-ups all over the place. However, I think you can upload close to 300 MB per file... which isn't too shabby.
I guess in short, it comes down to the accesibility of the user and the uploader of the file. Does it suck for those without premium accounts? Yeah, definitely. But in the end, it might take some time, but you still end up with the same great movie (or scene) and everyone ends up happy... and with a "happy ending". LOL There are some things in life you just have to deal with, I guess... and this would definitely be one of those things.
And to TexasGuy, I thank you for uploading movies scene by scene. It really does help those who don't have a premium account, as well as just allow those to grab the scenes they feel are the most enjoyable. Big kudos to you on this process (although, I'm sure it's a very time-consuming thing to do).
