Gaming Borderlands 1 and 2 GOTY editions question

[EmulateLife]

Does anyone know which disc is the main game and which disc is the DLC on both of these games? I want to download the main game but not the dlc. I assume the disc 1 on both is the main game but just want to make sure because I have slow internet.

thanks



Edit: just realized after posting I was posting in the Xbox One section thought I was in the Xbox 360 section. Mods please move.
