Record which remote and keys you used
Confirm whether you are holding Aero’s own remote or the television’s remote. Manhattan says the TV remote can navigate Aero with its direction pad and OK through CEC. A successful arrow-key action therefore establishes a limited control path, not full replacement of every Aero remote command.
Its current guide says channel up/down, TV Guide, number keys, colour buttons and playback controls are among the commands not yet passed through in this route. The TV may act on them itself, including switching to its own tuner for channel changes. That observation can look like Aero left the app even though the television changed its input context.
Compare with Aero’s own remote
Use the box’s supplied remote for the intended Aero guide or channel function and check whether it works there. Keep the programme and viewing app the same while comparing the two remotes. This separates a CEC command limit from an application that genuinely cannot respond to its native control.
If the television has switched to its tuner, return to the HDMI input carrying Aero before continuing the comparison. Note the selected input in the result so a broadcast channel displayed by the TV is not mistaken for the streaming channel selected inside the box.
Keep current capability separate from a future change
Manhattan identifies this as a TiVo-side limitation that it has raised with TiVo. That is not a dated promise that a particular software update will pass all keys. Consult current release information before treating an anticipated improvement as installed functionality.
For support, provide the TV and Aero software models, which remote was used and the exact key and resulting input. Avoid repeatedly unpairing Aero’s own remote when it works normally and only the TV’s CEC-passed keys differ. The focused comparison preserves a working controller while identifying the documented command boundary.
