I removed the number because "suddenly" it became a non-working number.  Just discovered that yesterday.  So we're stuck with the old numbers.  You might try 800-983-2811.  On the subscriber's manual they gave me at time of installation that number is on a label stuck to the front cover.

It IS strange that some folks have really great HD quality from Uverse and others do not.  I'm a stickler for picture quality....a serious photographer for most of my life.  Our HD is razor sharp.  On those occasions when I've viewed HD TV on my oldest son's 50" LG plasma it looks about equal to SD.  He has Time Warner cable service so I don't know if it's his TV or the cable company that is lacking.  But it sure doesn't look HD to me after what I'm used to viewing from our Uverse service.

In addition to the previously suggested calibration procedure you might download SomeJoe7777's "Uverse Realtime" application....install it.....run it....and post screen captures of the results.  We have guys on this forum who can then give you some idea of where your problem might be.  (don't look at me...I'm a dunce)  Also you might contact DAVID.  He heads up a team of tier 2 techs who try to help out with difficult problems.  You can find information on him and a number at the top of the "lounge" section of this Uverse forum.  They've helped a lot of folks.

As you've certainly already discovered......all HD channels are grouped above 1000.  SD channels are below 1000.  If you wish you could go to the options menu and use the channel options to hide all the SD channels.  Then you would not have to see them in your guide.  This doesn't make them inexcessible as they can be brought up by keying in the proper channel number on your remote.  It just makes them disappear from the guide.  I've done this, for example, to most religious & all rock music, country and western noise and children's channels as we have zero interest in them.

RE slow motion.  Well....yeah...that one's missing.  Not a loss to us but I can see where big time sports fans might consider it a necessity.  As for claiming that the Uverse DVR is no better than a VCR.....well, we've got both and I totally disagree with you on that.

Then...too....if all else fails there is always just going back to your previous provider.  I'm sure that is what my wife and I would do if we ever became thoroughly dissatisfied with our Uverse service.

Sorry about the bad phone number.  That one caught me by surprise and I didn't get it removed from my sig. until last night.
