Roamio Pro - HDMI output along with composite?

I did this with my DTV DVR but don't know if it will work with the Roamio.

Can I output over HDMI to my TV in one room (full 1080p etc) then hook up composite to another TV in another room and have it run both at the same time?

The DTV DVR forced both to run at 480i which sucked for my office TV.

LMK if you guys know how the Roamio handles this.

Thanks
