Here's my cbus hdtv experience.
Moved here in 2003 (Upper arlington area), started with time warner. Hated them. Customer service was aweful, took forever to get fox and abc in hd (that was a long time ago).
Moved to westerville/worthington area 2006. neighborhood only had 2 options for cable. Insight and WOW (no problem since I didn't have a great experience with TW). Ended up going with WOW. Great service. Hardly ever had any service issues with TV or Internet. However, as cable companies tend to do, my bill rose and rose to over 150/month for 2 hd dvr boxes and 12 meg internet. Then one day Insight knocked on the door and offered me the exact same thing I had with WOW for 80/month. Couldn't say no to that. Things were pretty much fine, however I started noticing my internet signal wasn't very good. Was paying for 15 meg with insight and most of the time when I tested on speedtest.net I would only get 3 or 4. They sent a tech out and fixed and it was fine for awhile but then started getting bad again. I think the main reason was the neighborhood was a very heave Insight neighborhood. One nice thing I found out about insight was they you can many free hd channels from straight cable out of the wall with no box. I've heard you can't do that with WOW. That was a nice surprise for our 3rd tv.
2 weeks ago ATT knocked on the door and finally sold me on their Uverse. At the time my Insight bill had crept up to just over 100/mo in only a year from the above mentioned 80. The att guy offered by 3 hd boxes (2 wired and 1 wireless) and 12 meg internet for 107... however when the tech showed up to install the first thing he asked me was why I didn't order HD. I was like are you kidding me, I Did! He said nope. So I got scammed by the salesman. HD service was another 10 a month so that took me to 117 plus tax (I called and complained but got nowhere). I did get $250 in gift cards.
Impressions on ATT Uverse so far...
Internet is very good and reliable for me. (Paying for 12 MEG and usually always get 11 when I test). I was worried about dropping from 15 with insight to 12 with ATT, but getting a consistent 11 is much better than getting 6 sometimes and 15 sometimes with insight. The whole house dvr is very nice, plus 150 hours of hd recording is way better than WOW and Insight. User Interface is lights year better than the arcaic onscreen menus of WOW and Insight. I also really like the apps you can download to your phone or ipad to run the boxes in your house, plus record things while away.
My one complaint (as many on various forums have pointed out) is that the HD picture quality is noticably inferior to cable. It's not terrible, but somewhat grainy and pixalated. I'm hoping to get used to it, but right now I'm haivng a hard time with it. I'm doing a great deal of research online. They used the existing copper coax in my house to hook everything up, and some seem to say running cat5 improves PQ, other say they just compress the hd signal too much. Regardless, it's a bit annoying, but apparently I'm in a 2 year contract (salesman failed to mention that) so I guess I'm going to deal with it. Overall I'm happy, just wish the PQ was better.
