Synergy V RT-U64CP Question

[scnrfrq]

I just picked up a new remote from TW. It's a new model for me - Synergy V RT-U64CP. It's nice, but I'm having trouble programming it to change the channels on my TV. The channel up-down and individual channel buttons only control the channels on the DVR. On my old remote you could easily change this. Has anyone figured out how to control the TV channels with this remote?
