no video's specifically for 1.5 that I know of.
Its pretty much a click and follow the prompts install.
1.4 over 1.5? 1.5 ads in new content to pretty much every category in game and refines existing files a great deal, locations, aircraft, vehicles, missions, etc etc If you like 1.4 you'll love 1.5
