I really want to buy a TiVo and just want to clarify a few things.

I have Fox Digital via cable in South Australia - so my Fox box would connect to the TiVo via RCA A/V leads (or other?), and the TiVo accepts this signal (ah la, a VCR) for recording and signal pass thru, then the TV connects to the TiVo via more A/V leads (or other?) to display the signal.
Now, the signal that gets displayed is either:
- live Foxtel (which includes all of the free to air channels)
- something playing off of the TiVo (pre recorded)
- or what ever the TiVo displays (like what an Xbox would for example)

The TiVo would also connect to my LAN (with an ethernet/cache card installed) and would recieve guide data from 'minnie' on a daily basis.Is this as simple as installing the ethernet/cache card and connecting it to the LAN - ie no set up invlolved? Will my macs be able to 'see' the TiVo HD('s) and be able to drag video off of them to view via Quicktime pro (with mpeg converter plug in)

When i get my TiVo and go out and buy a big HD (like 200GB) i need to install the ozTiVo image onto the HD. I have only macs at home and would like to know how i would go about installing the image to the HD with my G4 powermac? Is it as simple as downloading the image from 'minnie' and then dragging this over to the new empty HD (which i would have to install into my G4), plug the drive into the TiVo and its done?

Last question is - when i get a second HD for the TiVo i need to buy the correct bracket from expansis (or whatever they're called) and then does that drive get setup in the IDE chain as a slave (using jumpers) to the drive that already has the image on it (the original master drive) or do you have to put the image on to the second drive aswell.

Thanks for the help
any responses appreciated
