Movie downloading a second time

[Captain Planet]

So, I was on iTunes buying an album... I go check on the downloads and I see a movie being downloaded (one that I had previously bought a while back...) and I don't understand how come.

I know I haven't accidentally bought it again (if that's even possible). So why would this be happening? Should I just delete them from the download section? I can still see the original one that I have in my list...

Did this happening to anyone before?

You may have purchased a HD movie previously and the SD version is now downloading.

When you buy a HD movie you get the SD version also.

Well I know both version already downloaded. Besides, the downloaded show both the SD and HD versions. I just deleted them from the downloads... as long as I'm not charged it doesn't bother me... and I've got my movie so I guess iTunes is just being weird.

Yeah, it does that occasionally. You won't be charged again.

Yet again... it did the same thing today. I don't know if it just be better that I let them download instead of deleting them. Like, they took off from where they were last time it tried to download. But it does that only when I purchase stuff on iTunes.
