Does anyone else have a constant flashing on their HD channels. I mean, a constant blur/clear/blur/clear ? Usually it is flashing, but it is so bad on some shows that it looks like it is raining! Even old movies upgraded to HD looked better on Time Warner than actual HD shows on at&t. There has got to be a reason why, but the service guys who came out tried very hard and spent a lot of time trying to improve it. I don't understand it!

We are using component. The service guy tried HDMI, but we decided that the component looked better. I even notice it at the AT&T store display. You can see immediately that the quality isn't as good on HD as you see in a best Buy or something. My Time Warner HD picture looked so realistic, almost 3 dimensional. You felt like you were there. AT&T hd looks clearer than standard def, but lacks that 3d quality. I really miss that, but they only had about 12 hd channels. I wish I could afford to get Directv hd, i bet it's great.
