Thanks Rob, I'm admittedly a jackass. Once I looked at all my old Tivo links it started coming back to me, especially the Hindsdale guide. Tomorrow I'll probably just make a backup of my 160GB and 40GB drive that are in there now onto a PC, then have a go at the v4 install. I'll just save the backups so I can re-install on the drives if it goes awry. I can't afford new drives right now as much as i'd rather just start on a freshy and keep the existing for easy drop in backups. It'll suck to lose all those saved movies though... 40 of them at last count!
