TiVo made the design decision to continually buffer the two (or 4) tuners, so it is always recording hence the drive(s) are always spinning. This has come in quite handy on many occasions, especially since the 30 min buffers are independent. Given that current TiVo's have much larger HDD's it would be nice to have the option of enlarging the buffers to >30 min.
The standby feature is primarily useful for parental control of the TiVo. If you have the TiVo set up to block the adult channels
from the kids, putting the unit in standby after the adults are done viewing, resets the parental locks.
