[gord mayer]

I am useing a acer and have it hooked up to my HD tv via HDMI. However I also rebroadcast via a UHF modulator my sat DVD etc. I want to hook up my VGA with a adaptor to RCA inputs on this modulator and from what I have tried and read that I am unable to have both done at the same time. With computers you can turn that feature on but it seems with the XBMC program only one can be on at a time Any ideas
