Ever since the Fall update, we've had numerous problems with our Premier, ESPECIALLY regarding the 30 min CACHE: 1) If you hit record on a live show and are behind a bit, Tivo will jump to the end of your show when it's done recording....leaving you to have to go find your once "live" show in the playlist and then find where you left off. If your watching-while-recording sports, you get jumped to the end of the game....Tivo used to seamlessly deliver you from the live recording end to the beginning of the cache of the next live show!? 2) We used to be able to watch live tv a half hour behind (using cache) even if it needs to record another show in the next hour. Now, we lose the show we are watching (it dumps the cache) and it jumps to the next show in progress. Now you have to hit record on everything just in case you want to finish the show before it turns the tuner. 3) We used to be able to hit record and grab a few minutes of the previous show, even if it's gone into the next hour. So if you see something you'd like to capture at 9:50, you could still hit record and Tivo will record that PLUS the ten o'clock show after it. Not anymore. Now it dumps the cache and jumps forward. Been told by Tivo to restart and run tests. No help. If they replace it, I wonder if we'll just have the same issues. It all started after the UPDATE.
