Question for Computer Literate Friends

[5th Tuition]

Hey CBA's I have a question for you.

"Background"
I have been spending some free time looking at lots of "YouTube" video's. While I must agree with Mike, Kate Upton can really dance; I have been mostly watching Striper Fishing video's and trying to pick up any tips that I can use on the charter. I have also viewed a bunch of striper video's from out of state. I wanted to see if the northern states (or Virginia) do some things differently, and I could incorporate their success.
Not only have I been amazed at how many video's are available, I have been confused as to why some have trouble "buffering" so that I can view the video without stopping to buffer.
In other words, most of the video's start and run constantly from beginning to end. Some, start and run for 30 seconds, then they stop, the computer buffers some more, it starts again, runs for 30 seconds, stops, buffers some more, etc...

"Question"
Are these video's shot differently? Is it the camera? Is it my computer? What gives? Captain John has purchased a camera similar to the "GoPro" and he wants to shoot some PSCR video this spring. Is there a particular setting we should use, or more importantly avoid?
What say you fellow CBA's
