I’m not sure, but it sounds like you’ve discovered one of the remote’s ‘features.’ If you have just set up HT, you may not be used to the fact that once you’ve hit the DVD button, for instance, you have to hit the 950 (AUD) again to regain the use of the controls for the 950. Exceptions to this include the ‘volume control punch through’ as described on page 39 of the 950 manual.
As for additional gain, either set the main volume level slightly lower while you are adjusting channel calibration/trim, -10dB instead of 0dB for instance, (so that you have more room to turn the volume up later) and/or adjust channel calibration to a higher level, say to 85db instead of 75db on an SPL meter.
Be careful though. If adjusting the channel calibration/trim gives you 10dB more volume for DVD’s, everything else will also be 10dB louder for the same main volume level setting you may be used to using. I know the analog inputs I use tend to need a much lower main volume setting than DVD’s using a digital input. Switching from the end of a DVD I’ve listened to with the volume up to one of the analog sources without first lowering my main volume level can be quite startling.
If the remote is failing within the warranty period, Outlaw will replace it.
