Tivo is something I didn't really understand at first on how different it is from a regular Cable DVR. I understand really well how cable technologies work with my degree in Computer Networking as well working for Level 3 support at my local cable company. I read all the reviews on this TiVo box and it was somewhat puzzleing. Some of these reviews do seem to be one sided...either a huge grudge against the cable company, a huge grudge against TiVo, or they just love everything. I'm going to play neutral and try to break it down so that is may seemed more central opinion.
I have owned my TiVo for a few weeks, and right now there really isn't too much a difference between it and my Cable DVR. The main thing is, if you want to save money in the long run...and I mean a long long run, the TiVo is a better deal. If you want stuff to work right away, the Cable DVR is the best way to go. Here are my reasons why:
Cost: The cost of the TiVo is expensive, but can be worth it in the long run. Most Cable DVRs run between $15-$20. My Time Warner Cable HD DVR is $17 and runs with no problems. Now, if you think that just buying a TiVo will save you money, well, look at all the other added costs. You will need to get a MultiStream CableCard from your cable company and they most likely aren't free. Mine is $2.85/month, and make sure when the technician comes out to install it, that it needs to be a MultiStream CableCard and not a Single Stream. Single Streams will not work with this box and you'll just have to wait longer for your box to start receiving digital channels. Also you'll need to get a service plan with TiVo. Tivo has monthly plans starting at $15/month (add that to the cable card and now you're not saving any money because it now cost as much per month for the TiVo as your CableDVR did), or you can choose quarterly, yearly, or get it over with with one payment. If you going for cost, you mind as well just pay it off all together right away. So, $299 for the DVR + $399 for the lifetime service plan =$700 one time charge. Now do the math. 700 divided by 17 is about 41 months. It will take 41 months to match what you're paying for with your cable DVR. Hence, if you're going for cost, don't plan on upgrading the box for a long time, because you're just going to be losing money.
Winner on Cost: Both- Depends if you're okay on keeping a box for about 4 years or not without an upgrade.
Time: The time to get a TiVo fully functional is a process that takes weeks. You need to have your TiVo set up and ready to go before the cable guy comes out to install the cablecard. Then after your cablecard is set up, as long as you don't live in a Switched Digital Video (SDV) area, you're ready to go. If you live in SDV area, you'll need to sign up for a Tuning adapter through your cable company (their free if you have Time Warner Cable). Mine will be shipped to me when one comes available, hence I don't have it yet. Without this box, you won't be able to watch all your channels. SDV works by turning TV streams off that are not in use, so if no one is watching BBCHD, and you want to watch it on your TiVo box without the Tuning Adapter, you won't be able to watch it. Call your cable company to see if this is needed if you think about going this route.
Also, the TiVo takes a long time to download the guide and set your channels on initial set up, so don't be in a hurry. It takes about 1.5-2hrs for the TiVo to install everything.
Winner on Time: Cable DVR
Content: I think TiVo wins this category big time. With Amazon on Demand, as well as HD streaming from Netflix, its really nice. The only problem is that if you subscribe to premium channels like HBO, Cinemax, Showtime, or Starz, you're not going to get their On Demands like standard cable customers get for free with their subscriptions. Amazon On Demand has more choices and better prices than Cable On Demand. Their have been reviews on here that say you can not watch your Amazon On Demands right when you order it...this is false. You have to give it about 2-3 min to download enough content, then you'll be able to start watching it (as long as you have high speed Internet about or above 7Mbps).
Winner on Content: TiVo
Interface: I'm very partial to both interfaces. My Cable DVR has a nice looking interface, but its harder to navigate all the settings and options. The TiVo interface is rough. The guide isn't a clear as I would have thought for an HD Box. You can see the letters are fuzzier than HD quality should be. Both boxes fail at using the remote to search for programming. It takes forever to type in a show, or log into YouTube off the TiVo. I wish either one would develop a Wii concept for better interaction. The TiVo's is better at interacting with you. TiVo will help you find suggestions for your programming you like with the ratings on which you give each show. Plus, you can choose what to record off of TiVo's website, which is really nice. I know the cable companies will soon be coming out with this, but as of this review, they aren't out yet.
Winner of Interface: Tivo
Extra Features: So, each box has its special features. My Cable DVR has Caller ID on TV which is really nice and can't be done on the TiVo. Also, Cable On Demands and Pay Per Views will not work at all on a TiVo until they become Tru2Way compliant. TiVo's extra features include access to online vendors like YouTube and Netflix. The other really nice thing that TiVo comes with is the ability to transfer your recored shows to your computer so you can burn them to DVDs if you so wish. This is a very nice feature to have especially when you do networking like me. So, if you can give up Caller ID on TV and your Cable On Demands, then you'll be fine with the TiVo. Also, TiVo does have multi room viewing, but you'll need to have multiple TiVo's in order to do this.
Extra Features Winner: TiVo
Customer Support: Either way, if you have to contact either the Cable Company or TiVo for customer support due to technical issues, you'll probably won't be happy. We as Americans want our stuff fixed and working now, not until the box can be replaced or a tech to come out. So, you'll have to put these grudges aside for now. Remember, you own your TiVo box. After you buy it, you're responsible for it. You break it, its your fault. TiVo will be more than willing to help you with your box issues, but if it is broken by a power surge or a natural disaster in your house, its your fault, not theirs so remember that before you call up and and start screaming. If you have your Cable DVR, if anything ever happened to it, its owned by the cable company. They'll take their box back and give you another, normally within a days notice.
Winner of Customer Service: Cable DVR
So, in summery, its about a 50/50 match. If you prefer light monthly costs, Time, and Support, its better to have the Cable Company's DVR. If you prefer on the Interface, Extra Features, and not upgrading your box for 4 years, then the TiVo is a good direction to go. All in all, I give this box 3/5 stars and if you do decide on getting it, I hope you enjoy yours as much as I do mine.
