Downloaded to 550 megs of 1076,43 MB and shut-down on me....very frustrating to say the least...such a HUGE HUGE file...
May want to re-think this and break it down for example below:
If you choose to split the file up the best thing you can do is to RAR it up and break it into whatever-MB sized chunks you're looking for. It's a very simple thing to do and I assure you whomever is the one that going to spend the hours rendering out the movie is going to thank you because he's not going to have to go through hell trying to separate the thing into equal-sized pcs so they can be zipped.
For instance, say there are 6 parts, each 100mb:
Someone downloads parts 1-6
Then they extract 1 part (WinRAR will pc.the rest of it together automatically)
The user gets to watch full length movie, no interruptions, and has a single 600mb file.
Lastly, the compression on winRaR is better than that of zip. The end size of the file will be a little smaller.
