My problem with TiVo doing this is that they are, effectively, modifying the recorded program by inserting a preroll ad. Seems like they are violating some copyright and programming rights.This, 1000%. I don't have an issue with Amazon, Netflix, YouTube doing this. I have a major problem with Tivo doing this, and for them to compare themselves to any content provider/streamer doing pre-rolls is ridiculous.
It's stupid because they open themselves up to lawsuits about skipping commercials but inserting their own. Even if they win the suits, they are opening themselves up to legal costs.
But my real problem is that I'm betting this is not going to be quick or seamless. I've seen enough of their blue circles to know it is going to cause problems.
