I was stumped (actually bordering on being pissed off) trying to figure out how to turn off my TiVo when I first got it. Read through the manual, tried every setting, googled the crap out of it... I still can't believe TiVo didn't put an on/off button on the TiVo. Granted I can see why they would want the TiVo to be always-on but there's times (like when you're moving it) that it should have one. Most people are so ingrained to turn electronics off before unplugging them that TiVo should have put one in or at very least give ample instructions on the first few pages of the manual to tell the user that it's not necessary since the TiVo has a robust, journaled filesystem that is unaffected by power loss.
I hate having to pull the plug to power off the unit, but TiVo isn't the only one - most DVRs (and VCRs for that matter) never power off, they are put in a standby mode which disables the video output but doesn't stop recordings even ones like the SA8300 HD. Only like other AV Equipment TVs, AV Receivers, DVD Players, HTPC's, etc all have the ability to fully power down before unplugging the devices from the wall.
VCR's it's not a big deal as there's nothing really to be damaged by pulling the cord when it's in standby (recording setup is stored in EEPROM or some sort of static memory that doesn't require external power and wont be erased/corrupted by yanking the power cord.)
DVRs are more like PC's, you do have a HDD that you're potentially recording to when you have the device in Standby mode. It could be downloading guide data from the head end. And other potential activities. HDD should quickly 'park' the head when power interruption is detected, but this still gives me a bad feeling.
The reality is TiVo and other DVR makers seem to have done a fair amount of due diligence and making sure there is no ill effects from yanking the power cord with the unit powered on (whether in standby mode or not) but it still makes me feel uneasy doing it.
A button on the back that would allow the board to take things down in stages would be nice. But not given that a simple I/O switch in the back to physically disconnect the AC from the power supply would be effectively the same thing as pulling the plug, but I'd still prefer that as the transients are much shorter lived with that type of scenario.
