1. I get 14 HD channels all at full bandwidth 1920x1080 or 1280x720.
You get what the network source passes to TWC. TWC then compresses the digital signal. This is exactly what DirecTV does.
2. I get on demand which I don't care about but my wife loves.
I have multiple Tivo units, so I haven't used On Demand, but I could see how some people could like it.
3. I have the 8300HD DVR which is perfect for my needs(2 tuners, DD, 160 Gig HD, SATA capability now, and HDMI). Other people hate it but it works for me.
Personally, I found the SA DVR to be the biggest piece of !!!! I ever used.
4. And probably the single biggest reason. Road Runner cable modem! 8 gigabits down stream and a very respectable 400 kilobits/sec upstream for $40/month.
For me, my friends and my neighbors, Roadrunner has been nothing but problems. Slow speeds and constant disconnects. I switched to Verizon FIOS in November and it has been exactly what Verizon said it would be: 15Mb/s down and 2 MB/s up. I haven't had a single problem. It is also less expensive than RR. I'm also saving money because with FIOS I can use Vonage. My RR connection was so bad, that I couldn't stick with Vonage.
When I had RR, it was advertised at 6Mb/s down (not Gb/s). I usually got around 3 Mb/s down.
All of this isn't cheap $136 a month.
I did the research and DirecTV is cheaper and offers more channels. Especially the channels I want: ESPN2HD, GolTV, ESPN Deportes and Setanta. TWC does not offer any of these channels.
