To my limited knowledge on modding and IOS. Regarding just ciOS249, it is not needed to play burnt discs from the Disc Channel. You need 3 things:
Wii Drive capable of reading burnt discs
System Menu cIOS (i.e. 60) has the proper modules to allow reading burnt discs
You have the IOS installed that the game runs on
Probably wrong on this, maybe someone can chime in. Either way, cIOS249 w/ the prilloader stuff makes this all irrelevant (still need the Drive though ofc)
