...features on the 1 disc edition? I went to tesco today to get avatar and it said on the self 2 disc dvd, but when i got it back it was just a single disc version (it did make me wonder if it was 2 disc or not looking at the case since it didn't say or mention any special features) this raised two questions 1) what was actually on this copy? And 2) is there even a version with special features on it? i was told the blu-ray version had 3 discs but i don't have a hd tv so i don't think i should really bother paying extra that i cant use, so what is the best option for me to do to get this epic movie i love with the features i want to see?
