“When you installed Nero onto your PC you gave Nero permission to be the default player for DVDs. Nero is probably opening up all kinds of different things. Like mpeg, AVI and so forth.”
I did some googling and luckily found the answer as follows
Start > Control Panel > Switch to Classic View > Folder Options
Start > Control Panel > Appearance and Themes > Folder Options
Select the “File Types” tab. Let the list load.
Scroll down to “AVI” then click to highlight.
Below the list, find “Opens With:” press the Change button and change it to a different program.
That should do it. You may want to scroll down and see what programs open other various file types. Of course i changed it to Windows Media Player and all is well.(attachment)
