Sounds like you are the first nz TiVo user to get this new box. So as of yet, no one has tested the composite out,
but forums say it will not work. However, you can buy a macrovision defeater from amazon, but they are
expensive $100+, and no guarantee it would work. First issue would be to see if the TiVo can control the
sky box via IR. I have read somewhere that it is supposed to have the same ir codes as pace.

Also, not sure how 'live tv' works on the sky box. it can record 2 and display another one channel I think.
Hopefully the 'displayed' channel works just like a current sky box.
Cheers,
