TiVo owners, check out apps.tv
If you’re a Series 2 TiVo owner (sorry folks, not DirecTivo) then you need to get yourself a USB to WiFi adapter and check out some of the home media engine stuff. Photos and music is and has always been great for broadband connected TiVo, but I just played and beat a Sudoku puzzle using HME. Freaking cool.
The best way to manage your HME apps I have found is Apps.tv.
