I never thought a missing laugh track would affect the viewing enjoyment, but it unfortunately does. I watched the four episodes w/missing laugh tracks, and it`s similar to watching a hilarious movie in a theater w/100 people, as opposed to watching the movie by yourself. It just SEEMS funnier.It appears that Paramount may have halted shipping & production of the season 4 sets, judging from Amazon`s stated 3-5 week delay in shipping. Lets hope Paramount has recognized the error and will soon have corrected sets in stores soon.Other than this small problem, the season 4 set is superb. Complete w/no edits or missing epilogues.
