I can't say I had problems with the sound on Spidey. But the video I found lacking due to the crap that was crammed on the disc hogging up all of the space.
I felt that it was intentional so as to make a SB release easily look better. And when they pulled the same crap with xXx (only worse), I knew it was true.
I'm still puzzled as to why they've not released (or even announced) a US release in SB for Spidey. xXx came out after Spidey, and had a SB release just a month or two back.
