I have 6 Tivos and 2 minis and the TiVo BOLT VOX has the new Tivo Experience 4. I've had this for 6 months and I can say there's nothing I like about Experience 4. First, the guide set-up for the tv programs moves across the screen horizontally and not vertically like the Tivo Experience 3. It take more time to scan through the programs this way because it displays less of what's coming up and depending if the program duration is more than an hour, displays the same program twice as you fast forward through the guide. Very inefficient. Second, when I click on a program I want to watch, Tivo starts to play one of its own commercials. I have to click on play again in order to skip the commercial. Terrible. Third, when I click through my menu of programs I've recorded, it displays a picture or frame in the background of the TV show. I find this feature distracting. I also believe this is one of the reasons why the Tivo is slower and not as responsive. Kludgy. I've called to see if I can switch back to the Tivo Experience 3. I can but was told I would loose all of my programs. So I ordered the new Tivo Edge and plan on transferring my programs off the TiVo BOLT VOX to the new Tivo Edge. When this is finished I'll switch my TiVo BOLT VOX to the Experience 3, transfer back the programs from the Edge to the VOX, and send the EDGE back to Tivo for a refund. There are many other issues I have with Experience 4. It is a down grade from Tivo Experience 3. The Tivo team dropped the ball on this one. After 20 years of being impressed by the Tivo Team I would just like to know what happened.
