Can the 'enhanced remote' actually control my tv besides turning it on/off and volume? I want to be in a position to use the tuner in the tv by hitting the 'tv' button and changing channels on the tv then when I want to go back to the dvr+ I can hit input and get back on the hdmi input for the dvr+.
To do that you could get a "Teachable" Remote, they start at about ten bucks on Amazon and some are lighted. They're also "Programmable", but not all programmable's are teachable.
The Logitech Harmony series are the fanciest of those and I've had the Sony RM-VLZ620 for five years and it works great, no light but easy to 'touch-navigate'. I paid $20 but they're getting close to ten now.
You can do anything possible with any of your IR Remotes with one of those and store them all away and do everything from one remote. In my case, my TV has a Bluetooth Remote (no pointing needed) which I love, but can't teach it DVR+. It's programmable for Direct TV STB's, I need to try some of those and see if DVR+ might respond to its cousin's IR commands.
My DVR+ (115R version) Remote controls TV's On/Off, Mute, Volume and inputs and in turn the TV controls the AVR's On/Off, input, Mute and volume, so in that sense my DVR+ Remote controls my AVR. However to change AVR input to anything but "TV" (or its surround schemes, tone, etc.), I need the AVR Remote. To select DVR+ sound from PCM to DTS, I need the TV's Remote.
Dolby is grayed out on DVR+ input, my AVR ignores Optical Audio whenever there is an HDMI source available.
I like DTS better than Dolby, but if I changed HDMI connection from TV to AVR, I would get best possible sound from DVR+, just like I do with my BlueRay and BlueRay's sound quality makes that worthwhile.
???Remote Control Extender??? What's that, a higher output battery?
I keep my DVR+ Remote in my most accessible location (four 1/4" square double-stick pads stick it to my Tablet's keyboard, which is always beside me and thin remote doesn't interfere with typing. That way I don't have to pick it up or point it, just a one finger press to control DVR+ when TV is on. When I end TV time, I do use AVR's remote to change to XM Radio or Swiss Jazz, but before turning off TV and DVR+, I use DVR+ Remote to turn AVR sound down to a sleeping level.
