How do I set nero7 as my default Playa??

Answer 1

Mp3 example: right clk an .mp3 song and choose Open With. Browse to find Nero7 and clk it. Before leaving the Open With window, put a check in the box that says "always open this type file with this program.
You have to do this for each file type you want to open with Nero7. Change back the same way.

and it is Player ... not Playa

3 ways
1: open an explore window (just click on something so a folder is open) select tools then folder options.....go to the file types tab and find the extensions for the types of files you want it to be defaulted for Nero

2: go to the options area of the player and then file types, select all the ones you want

3: right click on the file you want to always open with nero and select "open with" then select the option to choose, then pick Nero application and check the box for always
