how about a user choice to disable the 30 minute buffer when i deliberatedly put the tivo on standby. this may or may not save on wear and tear on the harddrive, but it certainly quiets down the unit and generates less heat. in addition, transfers are faster between tivos when the buffer is disabled (you can verify by changing the channel to 0). and then there's this annoying message on the dual-tuner if you place one tuner on channel 0 while watching a show on the other tuner. it informs you that the other tuner is searching for a signal or something similar. that's fine, but the message does not go away while you are watching on the second tuner. please, tivo. allow us to disable the 30 minute buffer, especially if we intentionally put the tivo into standby state. and get rid of that message, too.
