Megan's Mom, The BEST TIVO is with Direct TV, and the Built In Direct TV tuner into your Tivo. It has Digital quality, and blows away the cable signal. I would like an 80 Hour one, but they only make the Direct TV version in 35 hour. I asked why; It seems that the 35 hour Direct TV is the same size HD as the 80 hour cable version, it just records at a higher resolution. I went to Our best Buy, and tracked down the one employee there who understood the technology (I got his name as well). He confirmed this. I will say that we lost a Tivo to lightning, while we were on a trip, and it makes an excellent boat anchor. To fix it would have been $50 more than a new one.
If you don't have/want Direct TV, I would try to get a free one from your cable company. You can also ask Best Buy online with your specifics.
Best Feature...Gotta be Pause Live TV. I saw the commercial and laughed. My cousin bought a Tivo and told me to stop laughing, it saves marriages. If my wife walks into the room while I am watching a show, I can give her the attention she deserves/requires, When you pause the TiVo, the sound goes off. You can rewind a few seconds and Voilà, you have room to skip a commercial...
Which unit to buy? The one that went out was a Sony. We replaced it with a Hughes. The units were virtually identical,
except
:note to Beast) The Sony has an IR link to automatically start and stop your VCR. The Hughes had the plug in the back, but would not support the remote IR. If you have a Sony VCR, the Sony would even start and stop your VCR for you. If you will be archiving, I recommend the Sony, if you won't even have a VCR in the same room, well, the units are virtually identical.
HDTV. There are Tivo Units that support HDTV, but none with the Direct TV tuner built into them. I am still waiting. If you have an HDTV, this might be an issue.
Up Front VS Pay Per Month? I paid it all up front, and when my first Tivo Died, they transferred the service to the new one. I am happy with it.
Buy one and hide it...I understand your desire for this to be a holiday present, so why don't you order it directly from Direct TV and schedule them to come out during the day on the 24th to install it? Or better yet, give it to him early but tell him he can't play with it until Christmas (or whatever Winter Holiday you celebrate) It is not Life Changing, but it is incredibly convenient and easy to use. (Gosh, I sound like a commercial; no, I don't work for them, but I am a satisfied customer. The only regret I have is about 12 hours of shows that were supposed to record when it went out. The Tivo worked so well up to that point that we thought nothing could go wrong.
