I bought a 32" LCD-HDTV (ILO) and had to upgrade my DirecTV receiver and dish. The Receiver was an additional $100. but the dish was free. However, contrary to what the sales clerk said, there will be a $10.00 per month additional charge to DirecTV (the first four months are free). The receiver comes with the basic setup - but suggest that in order to obtain optimum reception you should purchase an HDMI cable. There are only a few HDTV stations available. More to come in a few months.
After hooking up the HDMI cable, I found it made a buzzing sound every time I changed channels. I called tech support at DT and they said that there is a glitch in the compatibility of some new TV's and new receivers (now they tell me after I spent $31. on the HDMI cable) ~ and that there is very little perceptible difference between "component" reception at highest resolution and HDMI reception. (More info they failed to know about when I purchased HDTV).
Bottom line, the picture is a big improvement over the old analog TV and there is a difference between true HD broadcast and analog. I'm not sorry I bought it, but it was more involved than I thought it would be.
His wife complains about the distorted picture on the local channels, but my brother insists on having full screen so as not to "burn" the edges of the 4:3 aspect into the screen.
We had noticeable "buzz" at higher volumes - a friend suggested disconnecting the cable itself as a start! It immediately disappeared - no new receiver necessary (rats) - apparently it can be a grounding problem.
I'm set up with a few splitters but was able to track down a bad cable to fix the problem. Try going direct from the "wall" to the TV and see if that helps the buzz at channel changes? Hope this helps. :-)
We have not upgraded our Direct TV DVR yet, but the picture is a huge improvement. The curious thing is that my son hooked up the old set and surround sound/dvd/receiver in the basement to play dvds in the work-out room and the picture is almost as good as the new LED set. The old tv hadn’t worked that well for years, after being set up first by comcast and then by Direct TV. We would never have bothered to get a new TV if the set had been working that well.
