Switch between HDMI and Component mode troubles

I have the WD Live Hub connected to my Full HD Denon AVR through HDMI cable, AVR is connected to Full HD TV. I also have the WD Live Hub connected to my Full HD TV through component cable parallely. When I switch between HDMI and Component modes the resolution out from WD Live Hub resets to some default. I want WD Live Hub to consistently produce 1920x1080 output in either of the modes. Is this is bug?

Connect the Live hub directly to the TV then switch between component and HDMI if the resolution statys the same then the HD Denon AVR has compatibility issue with the HUb.
