no, you can't use CDRWin to write multiple ISO images onto one CD. i will explain: see, technically, an ISO (or BIN, in this case) is the exact rip of a whole CD. this means that all the data headers and leadins and stuff are copied from the original CD.
if you were to write two ISOs to the same CD while they are in BIN or ISO format, it wouldn't work because the data positions would be "fighting with each other". basically, if one BIN says to start at the 0:00 position, and the other says the same thing, of course there will be problems.
so to make a long story short, use two CD-Rs (they're cheap these days anyways), or first extract and then write the images on the same CD, if they fit.
