At 10:03 AM: Started going back through my Hulu history rating shows to see if I can get better suggestions till I noticed it does not seem to be keeping my ratings. Guess that was time wasted.
At 10:47 AM: Still trying to sort what is going on with the Hulu watched indicators on episodes too. Thought they had just stopped working in the TiVo app but while on the web site going through my history I see they show up on some shows and not on others. You would think the watched indicators would key off your history (just makes sense to the programmer in me) but they don't seem linked.
