I have season 1-7 on dvd. The other day I bought season 6 and 7 together. I decided to start from the beginning and watch them all they way til the end of season 7. Anyway, on season 1 disc 3 I saw an episode I have never seen before and I have watched the season dvds 4 or 5 times. It's the episode where Arthur gets a job working at danny's pizza parlor. Has this happened to anyone else? or do you think it's my dvd player?
