As do I....WYWH seemed to have a lot of extras on the quad mix (like the background singers coming in before the first verses of SOYCD...extra sounds in the opening of WTTM... ) As to the Mothership redux..that's a shame, I really feel the mastering on those discs were the most superior of all..I feel they are much better than what was done for the box sets (to my ears anyway...wish I could find something actual to back up why I may prefer them)

if you email them explaining the situation, I'm sure they will help you...every attempt with LZ I timed out until I ran out of chances, they are willing to assist you and they should be able to verify your previous attempts
