I have a file on my mac that i want to burn. its 699 megs. A video. I got a blank 700 mb cd but it wont let me copy the file onto the cd coz there is not enough space. On windows, the cd appears to have the full space it has. But when i check the info on the mac it only has about 660 megs of space. why is that? ive burned 700+ megs onto reg cd-r's before without problems on the windows pc. Why wont the mac do this? is there a way to resolve this? thanks for any helpful input.
