I have two UK Series 1 TiVo's seeking new homes.
Both units were working before I decommissioned them (when the original TiVo service was shutdown) but I've not tested them since. They've been stored indoors ever since though, so there is no reason to think they do not work.
Only one TiVo has a remote and IR blaster, so am happy to split the other if someone would like it for a spare. Neither units have HDD's, so you will need to fit a drive with an AltEPG image.
