Question: Does it have timeshift mode? I start recording show; 15 min. later, I watch in delayed mode, while still recording, allowing skipping commercials.
Document: I had a TiVo that could record two shows at once. I hate commercials and enjoy watching my favorite shows on my time schedule. With my old Tivo I was forever recording two shows at once and unable to watch a 3rd show.With my new Roamio I can record three shows and still watch a fourth show at the same time. I couldn't ask for anything more.
easy to set up recording and love the way the onscreen guide works. Say your on the  guide for the Discovery Channel. It will have about 12 hours of the differnt shows that are on that day. Makes it so much easier to look down the list an record any show you might want to watch later. I have 2 TiVo's in my home and one of the other things I like is I can be watching shows that I have recorded on the other TIVO.
Having now cut the cable cord, I've been having a lot of fun exploring my TiVo. Watching and recording local stations is GREAT!. The only DVR feature I would change would be to automatically record the last 60 min instead of 30 minutes of the channel I'm watching.And it's nice to not have to change the TV input in order to watch Netflix or HuluPlus. I haven't used Netflix yet but I have mixed reviews for watching Hulu. It skips most of the limited commercials (yeah!)
I like how you can watch tv in the top right corner, and look for a show or check to make sure things are recording and not have to pause.As always, I still greatly enjoy the tivo suggestions where it picks up movies, and tv shows it thinks I might like. You do need to thumbs up/down shows if you want to filter them better.
I called AMEX. Was told it would not cover the cost of the replacement  ($ 49). Only would cover the labor cost, since parts were still under the TIVO warranty (90 days labor, 1 year parts). Since labor isn't separately charged, I'm not covered. Think that stinks.Update. 105 days later.Well warranty is up by 15 days. TIVO doesn't recognize tuning adapter.
Does the job of pausing, recording and skipping through live TV very well.I use an over-the-air antenna and it is a great way to handle recording live TV.I also find the tuners are more sensitive that any of the other OTA tuners I have installed in my TV's.Still not happy about the monthly charge but I decided to live with it.
As a clergyman, I get calls at all kinds of times. Watching only recorded shows keeps me from being "upset" when "my show" is disrupted by a need from a parishioner. I just pause when the phone rings, and deal with the need, then return later to what I wanted to watch!
I love my TiVo because when I can't stay up late, I can record my favorite shows and watch them later. I can also record shows that are on at the same time so I don't have to miss one good show to watch another. I can also skip all the advertising.
My wife and  I have been wanting to cut our Dish network service for years, but didn't want to watch local TV with all the ads. When learned about the  new Tivo Roamio, we decided to order it and then cut the cord with Dish.My wife and love the guide which lets us see what is on now and six or more hours later. If we want to record a show, we can do it from this guide or the Tivo screen.
Tivo lets me keep a large stash of good shows to watch so i always have a good show ready to view. To top it off, fast forward through those annoying commercials! Even better, no more cable TV bill. I got an little square plastic antenna on Amazon for about 12.00, and I get plenty of channels. With TiVo you can set it to record a bunch of shows, so many, you will never have time to watch them all.
Answer: Yes, in either of 2 ways:1) If you programmed a recording, you can begin watching before it ends2) While watching live TV, it remembers prior 30 minutes automatically. You can pause for up to 30 minutes and resume. You can also rewind if you missed something.  Just don't get more than 30 minutes behind in "Live" mode.
