Assuming I'm paying for cable TV, and all of the series in question are aired on the networks I'm paying for, which of the following are legal? Should any be illegal? Are any immoral?

• I watch every episode of Series X as they are broadcast.
• I watch most episodes of Series X as they are broadcast, but occasionally I'll record an episode if I can't make the normal broadcast time, and watch it later.
• I have a Tivo, and record every episode of Series X. I watch all of the episodes some time after they are broadcast.
• I have a Tivo, and record every episode of Series X. I watch all of the episodes some time after they are broadcast. Sometimes I'll watch episodes of Series Y while my Tivo is recording episodes of Series X
• I have two Tivos (or one multi-tuner Tivo), and I record every episode of Series X and Series Y. The two series are only broadcast at the same time, so there's no practical way I could've watch both series without "time-shifting".
• I accidentally deleted an episode before watching it:
  • I borrow a tape of the episode a friend recorded from TV so I can watch the episode.
