I never thought it would happen - but TiVo has brought the "Skip Mode" functionality, previously an exclusive feature of the TiVo Bolt, to the Roamio line of TiVos with a recent software update. From TiVo:
TiVo Roamio users can now skip commercial breaks with the press of a button on over 80% of the most popular shows on the top 20 networks. A few minutes after a show has aired, a SKIP icon will appear next to the title in your My Shows folder. When watching a Skip-eligible show, press the “D” button at the commercial break and you’ll be back to your show instantly
TiVo has now brought two of its hallmark features from the new Bolt DVR, SkipMode and and QuickMode, to the Roamio line. The upgrade is coming as a staged rollout to Roamio boxes and supported Minis. TiVo says compatable devices that are network-connected should receive the update by March 10th. As a fairly recent Roamio purchaser I'm thrilled to see TiVo continue to upgrade the platform.
