Remote and Motorola DVR Problems

Question

I was connected to fios internet and tv on March 5, I have called tech support at least 8 times about the remote not working . I have had 3 boxes and 2 remotes sent to me and I still have the problem . I have a Sony Bravia LCD 40" TV
The first box was a Motorola QIP 72161 that came with the installation (remote worked intermittent)
I was sent a new remote same results
Sent a new box the old style 64xxxx remote worked but the hard drive was bad
New box Motorola QIP 72161 same problem
Tech support advised me I did not set up the remote codes properly (had same results it would work for a while then stop)
Tech support hung up on me
Tech support had me lower the picture settings advised me the picture was too bright and it interfered with the remote. She was very polite and helpful saying that this is a known issue and the problem is in the new Motorola boxes Sony, Samsung Sharp all are having this problem  (worked all day but not at night)
Tech support told me I had to move the box from out from under the TV still did not work and that was all the solutions they had. By the way the remote works with the TV off. Played around with the settings on the TV ended up increasing the setting to vivid and the remote worked the rest of the night. So much for the brightness theory. But alas it did not  work again this morning. Again the remote works with the TV off. Played around some more and you know when you first turn on the power to the TV you have a blank screen well the remote won't work then either. Although when I turn off and on lights I get a response one way Or another.
The attitude from the last techie is this is the way it is. I seems unfathomable that this is the response change your entertainment center watch a reduced quality picture or too bad.

You are welcome funkyybuda. This seems to be a "hit or miss" problem, some people say turning off the light sensor helps, some say turning off the "vivid" mode on the TV works, some say neither helps, etc. But apparently for some people, changing a setting on the TV really does help, I guess it just depends on your TV brand and model, or perhaps the specific STB you have. Strange.....but glad it worked for you  
As to why it works, the Verizon STBs use infrared (IR) for the remote to control the STB. Apparently some TVs generate their own IR signal for certain settings, like vivid or the light sensor, and the Verizon STB sees these signals and this prevents their reacting to the IR signal from the remote. So doing whatever you can to remove the IR from the TV, or reduce it, seems to solve the problem. I wonder why all STBs that use IR, from all manufacturers and used in all systems, don't experience this problem with TVs that generate their own IR. Just one of life's mysteries I guess....
