You didn't mention which version of Fibe remote you have; there are at least three different models in the field. Presumably, you have the so-called 'slim' remote, since that's the newest.
I have the Fibe PVR, the 'slim' remote, a Sony Bravia TV, and a Denon AV receiver. Once it was configured for a Sony TV, the volume buttons on the slim remote adjust the volume on the TV. I'm pretty sure I used code 0019, as shown in the Fibe manual.

In addition, the remote will control the volume level on the Denon (and hence the audio level coming out of my sound system) thanks to the HDMI-CEC protocol. (the Bravia receives the IR signals from the slim remote, and passes them on to the Denon over the HDMI cable).
Similarly, the mute button on the remote puts the Denon into mute mode. And when the TV turns on (or off), it relays the power command to the Denon which also turns on or off. This all happens because the Bravia and the Denon both support HDMI-CEC.
Unfortunately, it's not possible to configure the slim remote to do anything more with a TV, other than volume, mute and power. If you want more freedom, see if you can get Bell to give you the MxV3 remote. That's the model that was supplied with FibeTV before the 'slim' remote came out. Some installers still have a few of the old ones bouncing around in their trucks. The MxV3 is a 'full-featured' universal remote, and can be programmed to many different brands of TVs, DVDs, DVRs, VCRs, and AV Receivers. It's also a 'learning remote', so you can manually teach it specific IR commands from a device's native remote control.
