I have corrected the null originalairdate values for all episodes that had them, and the problem has cleared up for those titles.

Knowing now what the problem is, I looked at the database and saw that all of the movies I have recorded also have null original air dates.  If I go to one of the category lists, such as "War", and scroll through those movies, I  see the same behavior - the cursor suddenly jumps to a different spot in the list.

The list sorting algorithm has a definite blind spot when it comes to null values in the original air date field if one is sorting by original air date.  I would be happy to code and test a patch if someone with some experience with this piece of the code could provide me with some kind of guidance as to how it would be best to handle it.  Should the null values simply be ignored and some other field be used for determining sort order for that record?
