I am having some rather Bizarre behavior from my latest 880.
I have had an 880 at my other place for over a year and it has worked flawlessly with all my components (InFocus Projector, HD-DVD player, DTV HR20-700, Pioneer 84TXsi, Sony CX995V, & Xbox 360.

So I purchased an 880 for the HT I set up in a town-house in Vegas. The first remote I purchased worked the projector (Mits HD1000u), Sony CD-Changer, HD-Tivo, and HD-DVD player mostly OK... it seems to have a button issue where while watching TV and using the buttons occasionally you can push a button 4 or 5 times and it never sends a signal (no transmit icon shows). Also it would never turn the AVR on or off (Yamaha 2090). However, you could always turn the AVR on via the HELP menu or via the Device section.
I worked with level two for several hours and they could never get the AVR to function properly. So due to the button push issue they RMA'd the first remote and sent me a new (second Vegas) remote.
I loaded the old profile after charging into the new remote. Now the new 880 will NOT turn on either the AVR or the Projector? I have spent over an hour on the phone with level two and they could not figure it out either. They asked me to run some tests and respond back. I have done so and the following is the email I have sent to tech support.
After reading if any of you have suffered similar problems and can suggest solutions I would certainly like to hear them!!!!

Okay I ran all the tests per you request.
The results were incredibly frustrating and disappointing.
I hope the young lady from Toronto that I met at Cedia will be able to help. What is happening makes no sense at all.
My original 880 here in Vegas has issues where not all the button presses are recognized (no transmit icon during button press). Also that remote would not reliably turn on or off the Yamaha AVR (model 2090). However, it ALWAYS turned the projector on and off.
The NEW 880 here in Vegas.
Listen to Radio Activity perfect.. Turns on AVR and selects Tuner. Turns off every time from main silver switch or from the Power Toggle within the device mode. Power On/Off and Power On/Off Zone1 or 2 do not work
Listen to CD's Activity perfect turns on AVR and selects CD input applies correct sound field. Also turns off both CD and AVR each time silver off button is pushed.
Watch HD-DVD HD-DVD player starts, but NO Projector and NO AVR. You can turn on AVR from Power Toggle within Device mode (instant you push button) or from HELP button by answering question Is the AVR on NO. Selecting Silver OFF button turns off HD-DVD player, but NOT AVR.
Watch HD-Tivo. NO Projector and NO AVR. AVR can be turned on from within Device mode or by using help first time. However I attempted to use the HELP mode 12 times to turn on the projector and it does not turn on. I tried the ON and OFF buttons within the Device mode without success. I also tried the Power On and Power OFF within the Device Mode and they did not work either. I tried to use the Power Toggle selection within the Device Mode and it did not work either.
I then went back and tried the original 880 that I purchased for here in Vegas and when I selected the Watch HD-Tivo activity it turned on the Projector first time, but did not turn on the AVR. I could turn on the AVR with the HELP function.
These responses are very confusing and frustrating. How can the signals work from one remote and not another? Are you folks having a QC issue where you have seen this behavior before?
