That shouldn't happen. The sections for:

            if (episodeSort == "Id" && titleView && titleIndex > 0)
            {
                if (oldprogramid > p->programid)
                    break;
            }
            else if (listOrder == 0 || type == Delete)
            {
                if (oldstartts > p->startts)
                    break;
            }
            else
            {
                if (oldstartts < p->startts)
                    break;
            }

are checking if we have gone past the item while going backwards
through the list. This should only happen if the item had been
deleted. By breaking without incrementing "i" it puts the focus
on the item after the one that had been deleted.

This is the code that checks for a match:

            if (oldchanid == p->chanid &&
                oldstartts == p->startts)
                break;

If a program was stopped and restarted the startts' would be different
and it should stop on the right one.

When the focus shifts to the bottom item on the list, that means
that the check to see if we have gone past the item is incorrectly
true right away. If it didn't find a match and these checks always
failed, the focus would end up at the top of the list.

It would "always jump to the last show with the same ProgramID"
if the test was:

         if (oldprogramid >= p->programid)

because as it was coming up the list from the bottom, it would
stop on the first item that matched the programid without ever
checking the chanid and startts. Therefore it needs to be ">"
and not ">=".
