HD Channel LAG!!

HD Channel LAG!!

So I just got Uverse installed and everything is working on point except the HD channels.  When I am channel surfing thru SD channels there is no problem but once I get to the HD channels it becomes very slow.  Every HD channel I select the TV screen goes black or very distorted for at least 60 seconds often longer.  After the at least minute wait the HD channel loads up perfectly and works great until I change the channel.  Again this only happens with the HD channels, every HD channel.  Has anyone experienced this problem?  I have only had uverse for 2 days and really like it but no way am I going to pay for this to continue.  Any suggestions are greatly appreciated.

 

Thanks-

Re: HD Channel LAG!!

Over the last couple of years I have  not experienced anything like this. Nor, have I seen anything reported in either forum..

 

Could be your tv, STB or HDMI. Or, maybe the port at the VRAD. The only thing you can do is swap components. Then you should call customer service to have a tech visit. CS will probably have you reboot everything.You could try that before calling.

 

Sounds like you have only one TV/STB. You don't say you have the problem on only one.

 

If you are using HDMI try component cables  to connect between the STB and the TV.

 

Sounds like the higher bandwidth required for HD is giving some device heartburn.

Re: HD Channel LAG!!

Yea the Install guy was at the house for about 6 hours last night trying to figure it out with no luck.  I have not tried to switch from HDMI to component cables but will tonight.  Yes i definitely have 2 TV's(Plasma and LCD) with DVR and HD hooked up and the "HD channel loading problem" is happening on both of them.  I agree with that higher bandwidth causing problems, that is exactly what it seems to be doing, like the HD channels have to load or buffer before showing up....

Re: HD Channel LAG!!

If it is the same on both tvs, it is probably not the STB TV or connection between the two.

 

Are you coax or cat5.? If COAX it is more opportunity for a problem & harder to change by yourself (diplexer between NID and RG?)

 

If you have a direct connection between the NID and RG , you can try to eliminate your TV side of the network by disconnecting the outputs  at the RG and connecting one STB/TV to the RG by a short cat5.

 

Do you have pair bonding? - There is indications in the forums of problems with pair bonding. Since this is a previously unreported problem, it may be the cause.

 

You did not say if the tech swaped the RG

Re: HD Channel LAG!!

Yea since i have only had this for 2 days i am not exactly familar with all the terms you are using.  I have a coax and a cat5 coming from my wall into my RG(the vertical box with all the blinking lights) from there another cat5 runs into my STB.  I am not sure what "Pair bonding" is so i can not comment on that.  But yes the tech switched the RG and STB multiple times last night.  One thing i did notice after checking my AT&T site was that i am on the lowest internet plan 3mbps i believe, when i definitely ordered the 12 mbps.  Would this affect the TV at all or is it just used by my computer??

 

Thanks again for all the help.

Re: HD Channel LAG!!

Pair bonding uses two copper pairs instead of one to reach customers beyond the "normal" limit. I believe that this arrangement does not have an RG. The is built into the NID.

 

So, I guess my question now is - does the cat5 that goes into the wall feed the other TV or a PC.

You say you have a PC - How is it connected? Wireless?

 

So, lets say your PC is wireless. You have two TVs each with their own cat5. And, the RG to NID is a direct coax. Any possibility this coax has a splice or splitter?

 

In the sprit of double check everything, here are the only things you can do -

Check all your connections to be sure they are tight and do not have shorts.

Turn off the wireless

Disconnect the cat5 at the RG one at a time & see if the one connected works correctly.

 

There is a signal  analysis program for your PC, go to 

http://www.uverseusers.com/index.php?option=com_smf&Itemid=2

You will see the u-verse realtime application. You can try that. There are folks on that forum that can help you with it.

 

When you find the answer please be sure to post so others can benefit from the info.

Re: HD Channel LAG!!

I am going to try to make this as un-confusing as possible so please bear with me!

 

So I have a green cat5 running from the wall into the vertical box. I also have a black cat5 running from that vertical box to the STB on my "primary" TV.  My bedroom TV has a coax running from the wall to the STB and then a HDMI from the box to my TV.  My computer is wireless, I only use wifi when on the computer. 

 

That link you sent me seems to be only pc, I have a Mac, do you know if there is a Mac version?

The green Cat5 is probably coming in for the NID (the box on the outside of your house). The vertical box with all those nasty flashing green lights is the RG (Residential Gateway).   Think of it as a fancy router.  If it is powered off nothing will work.  I'm betting your problem is from using HDMI cables.  They have given a lot of people problems.  The ATT equipment just doesn't want to play nice with them.  Disconnect them and use component connections.  It took me almost a year to finally get my setup to work well enough to keep me from going back to DirecTV.  I can use HDMI for my PS3 and other equipment but I had to use component for the TV.  Hang in there, we'll try our best to help you (even if you are a Mac user :smileyvery-happy:)  I don't think SomeJoe has a Mac version of his program yet.

There is only a PC version. I too have a MAC.

 

Based on the desc of your wiring I believe you have the  green cat5 from the NID to the RG.

 

The COAX connects only to the other TV.   Therfore you could disconnect the coax at the RG, reboot the RG and the STB connected with the black cat5 and see if it is ok. If it is ok then your problem is in the coax connection.

Re: HD Channel LAG!!

Jim-

so come to find out I am already hooked up via component cables from the STB to my main TV so I do not think that is the problem...

Since it is only the HD channels that seem to have to "load" it really seems like a bandwidth/internet speed issue. I just went online and up-ed my internet speed from 3 Mbps to 12mbps I am not sure how long or how to tell when it changes but hopefully that will fix the issue...

 

Also if I use the green cat5 cable from the wall to the RG is there a point of having a coax cable running from that same wall to that same RG?  That is the way the tech left if from last night but based on what I am reading on here it seems that you would either have on or the other..?

You need to leave them both connected.  The green Cat5 is probably the signal coming in from outside to the RG.  The coax is probably the signal going out to your TV's from the RG.  If you disconnect the coax from the RG you should loose the picture to both TV's (or it will freeze).  As far as checking your internet speed you can use any of the free services for that.  Just Google "test my internet speed" and pick one.  I started out with 3Mbps and didn't have the problem you have.  If the issue isn't the use of HDMI cables I'm stuck.  I believed it was a "handshake" problem with the cables, but with component cables the handshake problem goes away.

 

Idea - can you borrow a Windows laptop from a friend or someone so you could run SomeJoes diagnostic program?

Re: HD Channel LAG!!

Alright so i unplugged the coax cable from the wall to the RG and the picture on both tv's still work just fine, but the HD channels still take about 2 minutes to load and the only thing from the wall to the RG is a green cat5 cable (although it is plugged into a phone jack not a RJ-45 on both ends). From the RG is an ethernet cable to the main STB and from there component cables to the TV.

 

I found a PC..i will upload the stats in a few minutes

Re: HD Channel LAG!!
