I picked this up today, and I was aware of the sync issues people were having, but having watched hundreds of spaghetti westerns and giallos, I figured I could handle it.
However, I didn't notice any sync issues at all during my viewing of the film.
I even watched it in 1080/24p. Perhaps I have a good copy or all those giallos have made me immune to watching anything out of sync.
Anyhow, this may be my favourite concert blu so far. Now I understand why Nirvana is so revered. It's amazing what they were able to do with just three instruments here. Such a full sound and intense performance. A powerful and yet professional live set. I think I will have to check out some of their other performances on DVD, since it's unlikely those will be released on Blu. Killer sound on this disc too - I watched it with the DTS-HD track and it felt like I was right there in the audience.
