In my specific situation, I had those IR pyramids from Radio Shack. Someone else in my building apparently got one of those video senders. So when my TiVo went to record Whose Line Is It Anyway?, the air was filled with RF from their video sender, interfering with my RF-receiving IR-transmitting pyramid, causing it to emit unwanted IR.
28 minutes later, they apparently turned off their video sender. This stopped the extraneous IR, and the TiVo was no longer blinded and could transmit. The channel changed 28 minutes late. My TiVo happily recorded 28 minutes of the wrong channel, then the cast reading the closing credits of the show in a style of the host's choosing.
The IR circuitry has only a single bus for two-way communication. It doesn't have separate Rx and Tx lines. As long as IR is being received, IR cannot be transmitted. As long as IR is transmitted, IR cannot be received. It's first come, first served, even if the IR received is garbage data. If either side monopolizes the bus, the other is blocked.
(Apparently my corresponding remote interference to their sender during prime time was more immediately annoying to them and they ceased using theirs. Meanwhile, I repositioned my equipment such that I can now detect when such interference is occuring and can adjust for it.)
The TiVo does wait to start recording until after it has placed the last digit in the transmit queue. The time that digit is actually transmitted is sigificantly later.
This is not new to 2.5.1. We went over this when 2.0.1 was released as well.
Perhaps you should address your concerns toward HBO if they're airing movies with nudity in morning cartoon hours. I haven't had HBO in a long time, but I seem to remember that they never showed movies that included nudity until the evening.
And just to make it clear, no, I don't work for TiVo.
