Directivo in Canada?

This is a very simple question. If I buy and integrated HiDef Directivo from the US and set up a 'legitimate' paid account either by getting a US post office box or with the aid of a friend who lives in the US, can I use the TIVO feature in Canada? Will I need to plug it into a phone line, either initially during the first time I power it up, or periodically after that? If a phone line is required, is it required for Directv or TIVO or both? I know TIVO operates in Canada now, but I know DTV does not.

So again, can I use a Directivo in Canada? I'ev been scouring the web for hours and I can't find anyone who says they have this setup.

Thanks,

Rob
