Streaming Videos start well but then just constantly jumpy

Hi there

New user, first post.

I've went through some of the tutorials and done a few things I never heard of, or at least I understood and knew what I was doing.

For the last good while I have been unable to watch streaming videos without having problems. For example there is a UK (Scottish) TV player called stvplayer that I try to watch programmes on but its just a waste of time, I barely get 1 min into it and it is so choppy and jumpy.

I tried a few fixes last night but it only marginally helped.

* Unchecked hardware accelerator on Flash Player
* Connected to router using Ethernet rather than WiFi (this had the best positive effect)
* Battery setting was set to Power Saver but this was changed to High Performance

Youtube works perfectly.

I also just done a scan from the tutorials (SFC /SCAN NOW) and it has found corrupt files but access is denied to the log file.

Is it simply that my laptop is just not good enough?

Hi again, help please

Cheers guys

Sometimes streaming problems are on the other end.....Server overload etc...YT is Google=BIG servers.....
