The problem with CDRWin is, many people can't find a good crack for it, and download an ISO file which was copied with CDRWin, and since they can't burn the BIN file with CDRWin due to their lame crack which causes coasters, they need some other way to burn it... this is in most cases. Not saying it's all of them

Who knows, maybe he's having issues even running CDRWin with ASPI layer problems or whatnot.
