I'd set up a Season pass for TV3 News and TV2 Shorty and all seemed okay for a while.
Then Shorty stopped recording and now the News. After investigating I found details in the To Do List saying they won't or didn't record because the same episode appeared in the Now Playing list or to do list within 28 days. And to change Recording Options to Show All (With Duplicates) which I've done.

Does this mean a Season pass is only good for 28 days with Recording options as 'First Run or repeats' (which seems the default)?
Should the changes I've made be good to record indefinitely? So one all okay on 1st day.
