I bought this in December and have just now gotten around to making it all the way through it. The season finale on disc 7 has some audio problems. The sound seems to be very left channel heavy with very, very little coming out of the right. Also the dialogue seems to have a slight echo to it. I've tried this on other players and the same thing occurs. The rest of the episodes in the set are fine. Has this occurred with anyone else? Also, any suggestions on how/if I can obtain a replacement disc?
