movie channels are in widescreen

Press menu, then go to options and then select "TV screen resolution" for whichever suits you best. You probably want one of the two towards the bottom.

If not that, then it's probably some setting in your TV...but check the U-Verse settings first.

Been there done that.  Even the tech did the same thing with us today.  It only happened after we got an additional wireless TV receiver and then they sent a new WAP if I got that right.  They even sent a tech two weeks ago to assist us with the install of the wireless and he saw the widescreen issue.  Today they told us many customers are complaining about it.  Strange

When you say "in widescreen," what does that mean to you?  Do you have black bars at the top and bottom of your screen?

How is your TV connected to your TV Receiver (coax, composite, component, HDMI)?

Which "movie channels"?  800-999 or 1800-1999?

Is this happening on all of your TVs, or just the new one?

All of them since I added the new wireless receiver.  HDMI  There are 17 different movie channels of HBO, Showtime, Cinemax and Starz that are HD in their name however are shown with black bars at top and bottom 

It has stumped even the techs....it wasn't until we installed the new wireless and the new WAP they sent with the wireless that it started happening.  

Is there any difference in how the 8xx channel displays vs how the 18xx channel displays?

How do you have the Resolution set on the receiver(s) ( Menu> Options > System > TV Resolution )?

UPDATE: Yes, I realize you said you checked it, but you didn't say what it was.

I'm suspecting you already know this, but keep in mind that some movies in the 1800 channel range are shot at different ratios. Even on a 16x9 TV, you'll get black bars at the top and bottom.

But I suspect this isn't the problem.

Are you through answering our questions here?

We have not gotten any satisfaction from ATT as far as a resolution.  We discovered today that we have two different models of wireless receivers and was just asking for more information.  They tell us its our Tv's

If you think it is a duplicate than so sorry but I thought this was for assistance with our issues that are still remaining.  They were supposed to call us back within 2 hours of our last phone call this morning and we are still waiting.

Guess this forum isn't what we thought it was

This forum is community support... AT&T users helping other AT&T users.  It is not AT&T Customer support (although they have a small team of employees assigned, they can't keep up with all the posts, so don't count on them responding).  When you create a new post about a related issue (as you did), you spread out the information needed to try to solve your problem, someone may read your new post and not have the background information that's already present in the old post, leading to the same old questions being asked again (but perhaps answered this time).

So, we ask what we think are relevant questions based on our years of experience (much more actual user experience than the AT&T employees on support have) and will use the answers to those questions to guide our suggestions.  There are things we cannot do, like send you a new receiver, but we can tell you when that's the right solution (whereas many of the script readers would do that first thing because they're authorized to do so when they get to the right box in the script and that let's them get off the phone and to another call, and they're paid to answer a lot of calls).

Yes, there's two models of wireless receiver. There's a model ISB and a model VIP. Each one has four numbers after it. I think the ISB is 7005.

However, the software the boxes run is the exact same.

He's referring to another post he created where he mentioned that he has ISB 7105 and has now received an ISB 7005 and wants to know if that could have caused his issue.

The mystery issue has been solved but not resolved.    Since we added on an additional receiver, ATT decided to increase our streaming ability from 3 or 4 to 6 HD ??? and increase the speed of streaming assuming we would need more capability.  This however causes the viewing picture to decrease due to pixels.  So as we understand it as you increase the number of receivers they will increase the streaming capability without any notification to the customer.   Now, as explained by the tech they cannot reset us back to the HD capability what we had.  This really doesn't make any sense that a customer would have to give up the quality of viewing to have more capability to stream.  

He also explained that if we would switch to ATTTV we would have the same since we would be at 3 receivers and need 6 to stream.

We are rather confused.

As far as I know, it's the newer DVR with the 6 streams ability. I've had an older DVR ever since I've had 1000 Mbps and I'm still at 4 HD.

With AT&T TV, I believe you can record unlimited streams, but can only be tuned to 3 live streams at a time. Anything else would have to be through the TV channel's app.

It's my understanding that the DVR for AT&T TV is really small *plus* shows automatically delete after a certain period of time.

Because U-Verse is no longer available to new subscribers, if you switch away, you cannot switch back.

@Southernhome , that explanation smells of being made up on the fly by someone trying to get you off the phone.  U-verse has SD streams of 2 Mbps and HD streams of 6 Mbps.  There is no other packing.  You can be assigned more streams capacity; you might want to check your DVR's system options to see.
