Pretty sure Season Passes are Call Letter/Channel Name based, I.E. USA, FX, HBO, KUTV, KNBC etc.
As long as the stations keep their call letters, you'll should be good.
A few of us had Season Pass problems when FX changed their name 6 months or so ago, but kept the same channel number.
They used to be F.X. or FX! or something like that, and changed to whatever they are now.
