About KROQ 2010, i got it directly from Diego back to 2010 i think, it was broadcasted in HD but as far i know, no one HD recording surfaced. They listed as a DVD, because Diego doesnt have one HD Recorder, so he recorded it with his DVD Recorder.
About the Transformers 2 Premiere, the dvd version from MTVNHD was circulated between the traders, but im not sure if this is a real dvd.
