I am pretty sure it's not possible: the tivo hardware isn't designed to shut down - it's designed to keep running 24x7 and it makes every effort it can to do that, so even if you were able to do the equivalent of linux shutdown, the hardware would just say, "hey, the system has stopped working", and start it all up again.
Yes, that's my sense as well - I've never come across any mention of it anywhere
In any case, if you were to achieve this, how would you start it up again?
Well that's a very good point! I suppose I'd been thinking of the TiVo as being a little like my PC server, which I can power it down, and then just switching on the power starts it powering up.
I guess this model doesn't fit for the TiVo
Reason I'm asking is because, for 5 or 6 years, I've turned off my TiVo & Virginmedia box every night at 1:30am and then switched it back on again at 5:00pm (except at weekends) using a timeswitch.
Being able to shutdown via software would be a much more flexible solution...
I rarely record anything in the daytime, and only watch TV in the evenings/weekends mainly.Actually I don't watch too much TV really: less than 8 hours/week generally. The TiVo/Cable box is quite a power hungry combo.
