As you can see from my signature, I've treated myself to a new PC. The video editing problem wasn't the only reason for this but it was a contributing factor.
As far as I can tell from my specs now I should have no problem, but guess what, the video remains choppy!!
I did all the prep steps before install because as we know, out of the box PCs are completely out of date as far as drivers are concerned, My Direct X is up to date, the video and audio drivers are up to date and windows is up to date but still the same problem.
I've encoded using hardware and software, I've converted the file to another format and tried to work with that, all have proved fruitless.
Can anyone help with this?
