OK ppl, another fix/setting
Got DVD working fine using powerdvd, and i've moved the Radio from the first screen (i dont use it) and put DVD in its place, so its on the first page, button 3.
Change or Add the below line in menu.txt
&mainbut3=DVD@icons\dvd.png@LOAD;powerdvd_player.s kin;C:\Program Files\CyberLink\PowerDVD\powerDVD.exe;DVD&
NOTE: &mainbut3 is the button location
this will work the same for windvd, just change the location
PS this may have been covered before, cant seem to find it.
