Just cut and paste the following into a new text file, save it as test.reg, then merge it into your registry:
---------CUT BELOW HERE-----------
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\iTunes.m4p\shell\Convert]
[HKEY_CLASSES_ROOT\iTunes.m4p\shell\Convert\command]
@="\"D:\\Program Files\\m4p2mp4\\m4p2mp4.exe\" \"%1\" \"%1.mp4\""
---------END CUT ABOVE HERE---------
Change the path in the above line to where you have m4p2mp4 located.
This will only change one song at a time, meaning you can't right click on 20 songs at once and have them all convert. It's still slow, but at least you don't have to type in commands for every single song.
If you need any help with the above stuff, don't email me or post a reply. Since I'm not sure how legal m4p2mp4 is, I have dumped it and gone back to the method of burning a CD of the protected files through iTunes and then ripping the songs off of the CD. So since I don't have the program anymore, I can't provide any support for anything.
