Gratitude Monday -- Too Smart Technology Edition

We watched a very pleasant movie on TV the other night, Salmon Fishing In The Yemen.
It was recorded last Monday and we watched it a few days later.
I am grateful to have seen it, but more than anything I am confused as to why it was recorded.
Finding and setting programs for the PVR to record is my duty and I take it seriously.
This movie was a total mystery to us on many levels including we'd never heard of it and had no reason to record it.
Near as I can figure it we're the beneficiaries of "Too Smart Technology." That is, after monitoring our viewing habits for six weeks the PVR thought the movie was something we might enjoy.
It was right.

I am sure there is a prosaic explanantion for the above.
Malfunction of some sort, presumably. Or my finger slipped.
But until it is otherwise explained I am going with the above and hope that any choice it makes in the future is as enjoyable as this one.
