Hdmi video glitching out

what type of connector are you using HDMI or DVI and optical audio or super video andRCA

hdmi sockets are faulty on the dsp board - repair - replace dsp board

I put the tv on av to watch a dvd. I now want to watch tv and it will not change from av to tv. I have a universal remote and it does not register of when I put it on tv it goes back to av

Your'e losing digital data from Dish or the DVR. Since even live TV is through the DVR it is always a potential problem when anything glitches. That it doesn't repeat on immediate rewind/playback says the data made it to the hard drive ok.

The Denon is only defaulting back to an analog audio feed upon loss of the digital (preferred) one.

If it affects the video AND audio simultaneously the cause is something common to them.

I'd look at HDMI cabling into the Denon from the DVR.

Don't blame the Denon just yet.

My $.02:

I'd skip the video right past the Denon to the TV/Monitor even if it means using component cables instead of HDMI, but keep digital audio coming in from the DVR. Added cabling and connections never improve anything. Plus, HDMI cables are expensive.

It would be interesting to see if the problem comes back and affects only the audio or the video.

If you use optical cable make sure it has smooth flowing curves and no small-radius bends that would lose light power.

connect the bd direct to the tv

Sony has a firmware update out to fix this.

the sound chipset on the mainboard has problem.you can buy a USB sound card and test the audio with that .if the problem moved use it or change the sound chipset from mainboard.

it is not your hard drive
you have to reset the video setting and it will work again Hdmi is different on each tv so you have set this up again ok let's do this with the unit off turn the main switch on the back of the unit connect your Hdmi cable to your tv now place your finger on the front on/off switch keep your finger there ok now turn the mainswitch on the back of the unit the playstation turns on but don't remove your finget yet wait about 4 seconds or until your heard another bip (not the one when the playstation turns on) once you heard this bip remove your finger before the playstation turns off if you let it turn off try again all of this but if you remove your finger on time just wait few more seconds and bingo you have picture again using Hdmi

The problem is your cable box. I know you said you replaced it, but I work on TV's everyday and, sorry to say this but cable box HDMI outputs have serious issues, like no or intermittent sound and video. I have seen customers exchange their cable boxes 5 and 6 times and still have the problem. Your best bet is to use the component outputs of your cable box, visually you will not see a picture difference between component and HDMI when using a cable box. Your other solution is to get satellite; I have NEVER seen an HDMI issue with a satellite box

It may may the the AT+T box is really not compatible with the AVR or the Pioneer.

Check the specs on those input/outputs for the Ubox and the receiver.
See if they agree. If so, try another hookup method like HDMI ( which carries the audio too)
