I don't know what's going on there, but it doesn't surprise me that CEC is not working right for you. I've tried to use it several times in the past but got bad results. However, I have my DirecTV dvr plugged into my Pio SC-1522 cbl/sat hdmi input, and I have no problem using the DirecTV remote to control volume and mute on the AVR. So if that's what you want to do, it should be possible. (But if you want that remote to control TV volume when the AVR is turned off, that's something else -- that might require you to switch the remote to TV mode.)
The D* remote controls 4 devices: D*, av1, av2, tv. You want to set av2 to your Pio receiver and set the Vol button to punch through to av2, so you can leave the remote device switch in the D* position and still use the Vol and Mute controls for the Pio AVR.
I used my D* DVR to set the av2 device to the Pio AVR, using menu > Settings > Remote Control > Program Remote > Change AV2. The DVR did not know my exact Pio model, but I used "vsx1122k" (I think), and that worked. You should be able to set volume punch through on the same menu page, by going to > Advanced > Volume Lock.
The DirecTV web site also has a help page for setting up your DirecTV remote.
