In most respects TiVo is much better than V+.
Even the base TiVo has a larger storage capacity. You can record three things at once whilst playback something already recorded (you can timeslip something being recorded as well). Series link is great for so many of these programmes that stop /start through the year. The guide seems more responsive than V+. I could go on. Only downside is you end up recording so much stuff, you just don't get time to watch it
