TiVo in the US has quietly retired the Adobe Flash and Air code underpinning those TiVo screens with a new July update.
The new software promises a significant boost in interface navigation speed, having been re-built in the Open Source Haxe. In addition to being faster, the new user interace also adds a new "My Shows" column within which the viewer's favourite content is gathered up (see video above).
This move from Flash also opens the door to TiVo one day running Cloud services on Amazon Fire TV, Xbox One, and other platforms. More details on SlashGear.
I don't know when Virgin customers will be updated.
