...you do realize you can make OPs "All Channels", so this problem is almost entirely gone nowadays..
Though I probably still have some channel-specific ones, often if I'm updating one, I'll then change it to All Channels.
I realize this can affect those of you who record reruns. (The vast vast vast majority of my OPs are first run only.. I have a few of them, like "Naked and Afraid", that I often delete en masse to make space, then let it record reruns...)
