Here's my expanded opinion.
It's okay to download videos provided the following.
Videos being t.v. episodes and movies.

1) It's done on a broadcast channel, meaning the lower stations. Anyone can basically get these channels.
2) The commercials aren't removed, out of respect for their right to advertise for compensation of showing it for 'free' basically.

Or if it's NOT ever shown on television anymore in your area, on any of the possible channels you can order, AND it's NOT out on video in stores availible to you, then I think this situation is okay provided commercials are left in. This situation is if someone decided to record it on an upper cable channel, and decides to put it out for all to download if the show is off the air and not in stores.
