I don't think that really counts as hoarding.

Hoarding is more getting hold of data/films/tv/music that you're not expecting to get around to watching, but feel like you want a copy or that it is of cultural relevance.

e.g. I grabbed a copy of Sátántangó due to it's fame/importance, but I'm unlikely to sit through 7 hours of it.

Or more recently, I grabbed a better quality copy of the original Green Hornet series that I'm not going to bother watching.
