The company will withdraw its support for the boxes in June.
TiVo has followed up its deal with Virgin Media by withdrawing support for all of its Series1 boxes in the UK.Sky customers were exclusively able to purchase TiVo's first generation of digital video recorders (DVRs), which were manufactured between 2000 and 2002.
Since then, the equipment has not been sold and new accounts are no longer being activated.
Having been in operation for a decade, the boxes will be discontinued from June 1st 2011, with TiVo no longer providing them with electronic programme guide data.
This will reduce the devices to limited or no functionality, although viewers will still be able to access previously recorded content.
Users have not been billed since last November and will be able to access the service without charge until June 1st.
Virgin Media unveiled details of its TiVo-powered offering late last year. The set-top box is equipped with one terabyte of storage, capable of holding up to 500 hours of content.
