The latest episode of the Gadget Show has compared Sky,VM and BT's boxes. Tivo didn't fare very well with the interface being described as 'clunky' (even after the latest update)and the iPlayer being highlighted as a major issue which VM haven't solved (where it works fine on other platforms).

Strange VM don't seem to acknowledge the widespread issue and keep putting this down to individual faults.
Beginning to think this problem has been going on for so long ( ie years) that there isn't a solution and Tivo will never handle iPlayer. Either we'll have to wait for a new box, or VM will have to reconsider how they deliver catch up for BBC programmes. The Sky Box seems to download programmes before playing, couldn't Tivo be configured to do this ?
