This has been addressed a little before but wanted to check in to see if there have been any advancements... I recently moved my hr20-700 upstairs to replace an old tivo unit. The HR20 unit is noticeably louder than the old unit. Is there any way to turn off buffering in the middle of the night? I do have it set to record a few of the latenight shows like letterman and conan as scheduled but for before and after that is there any way to quiet the darn thing down?
