I am confused about using "Season Pass" on my Premiere. My wife has certain shows she wants to collect all episodes of. An example would be "I Love Lucy". Episodes air on at least three different channels in our Comcast lineup. I was hoping that setting a Season Pass for Lucy would grab all episodes on whatever channel was broadcasting same. Apparently not?? Seeing that likelyhood, I tried to set up a second Season Pass for Lucy shows airing on another channel. The Tivo would not let me it seems. It did not produce an error but did not create the season pass either. It would only allow each airing to be setup to record individually. What am I missing and what am I doing wrong?
