Stretching is the name of the game. I like the idea of TiVo, but to qualify as prior art, we need a publication. Simply find a product user manual (non-patent literature). Also, TiVo has many patents that also may disclose the ideas we're looking for.
The TiVo certainly downloads data when it records, where download is the transferring of data (audio and video) from one computer to another. I'd have to look at an early TiVO manual to see how well it meets the channel depth limitation. Further, the pre-defined channel is a tad tricky, but the TiVO box somehow knows what a season of content looks like. Is it pre-defined? Maybe. Maybe even the consistent name of the show from the guide information gives us pre-defined.
So independent claim 1 could probably be knocked out, but dependent claim 3 and its children would be novel limitations over our imagined TiVo art.
