ok i had to installed some dvd software yesterday and now i have it seems to load up any videos i have through this dvd playing software rather than windows media player, now i wouldnt be bothered but the dvd software takes twice as long to fully load up so i wanna change back to media player as my default player if i can?

 

in media player in the options menu (on the tools menu i think), theres a tab where you can reassign what you want to media player

 

jobs a good un! cheers mate
