I'm really confused, I put set 1 in group 1 and set 2 in group 2, then hit create .iso and it made the .iso file. I burned it to a dvd-a and only set 1 was on the dvd-a, where did set 2 go? I realize I must be confused somewhere but I just don't see where I missed it. The wavs of set 1 and set 2 are 5.44 GB so naturally it won't fit on one dvd-a. Can someone help me make the connection?
