Thinking of Switching to FiOS TV

I am seriously thinking to switching to FIOS TV. I currently have FIOS Internet and phone. I have been deal offers to go to the triple play and I may just pull the trigger on it. They look to have a very good channel offerings and the receivers seem good also. I currently have DirecTV and am happy with them. One issue I am having is that trees are starting to interfere with the signal. The dish is on my fence and I could get them to move it to the roof to solve the tree issue but I am afraid snow/Ice would become an issue this winter and no way to remove it.
I was just wanting some input on the pros and cons of FIOS TV? Is it reliable most of the time? Service good or bad if I have problems? The offer I have now is for a whole home DVR with no charge for a year. How much recording copacity does that have for SD and HD? Also would get a set top box. I am assuming I can access the DVR with set top box? When Verizon comes to install the TV service I am assuming they can use the cables currently used for DTV? I saw a video they had about this and it seems they can.
I would also be getting the Ultimate package with these receivers.This would save me about $50 a month from my DTV bill now plus more channels than I am getting currently. I believe it's a very good deal.
Any input would be very welcome. Thank you.

 

Thanks for the advice. I have Verizon scheduled to install for TV on Saturday. I am going to just suspend my DTV service for as long as they will let me just to make sure everything works out with Fios.

 

I had Fios TV installed Saturday. Everything went very well. The tech got there at just past 11 am. My window was 11 -2 pm.. So that was great. The install went off without a hitch. He installed two boxes in just under an hour. He was a very good technician. He did his job efficiently,professionally and was very friendly. I got a whole home HD-DVR and a set top HD box. The whole home dvr is a Cisco CHS 435. Just using it for a couple of days it seems great. Great picture quality. Better than both satellite services I have had. Looks like it has about 200 hours of standard digital space and the tech said it had about 100 HD hours. That's better than any previous DVR I had ever had. At first blush this seems like a good system I will be happy with. I was not that disatisfied at all with DTV but this saves me $50 a month the first year and $30 a month the 2nd year. With taking on some extra debt lately I thought this was a good way to save a little each month. I did suspend my DTV service until December just to make sure everything works out well with Fios. Overall it was an initial good experience. Thanks for the input of the two posters that took the time to answer some questions for me.

 

The free preview for MLB Extra Innings just ended for Fios. I was not impressed by how they do EI. None of the games were made available in HD. There were a few games that had both broadcasts but not many. Last night I tried to DVR the Reds/Dodgers game and it was cut off after an hour and 19 minutes. I don't know what happened for certain but I suspect they cutoff the free MLBEI at about that point. I'm glad I can get MLBTV and not worry about the FIOS version of EI. Not impressed at all with this aspect of FIOS.
