Youtube videos and my scroll pad keep sticking

Question

When i scroll down using two fingers on my scroll pad or whatever you call it it pauses for like a second and then its fine again. It also does it when i'm typing and it does it reallly frequently but for like a nanosecond. I also realised it does it when i'm watched youtube videos, and it does exactly the same thing, like the sound continues the video just stops for a second. I'm guessing their all connected but i just wondered if anyone knew how i could fix it cause it's so annoying!
Thanks for your help.

It's a function of signal quality and how much other stuff you may have open.
Wifi or 3 g?  Both things that you mention are streaming, so you need a decent signal to get decent results.  If wifi, then see what else you might be doing that is using processor or network resources. 
Double tap the home button to see the task bar.  Touch and hold any of the icons until they jiggle, the delete them by touching the minus sign.
Grab an app like speed test, and see what your connection speed is.  I have found that anything less than 1.5 mps will lead to spotty video streaming.
