Can I stream video to my projector from pc and surf on the internet at the same time?
You can if the projector is is not the only 'screen'
Yeah, I have separate tft-screen. How this can be done? Do I need any special programs for it?
Well no. Get the latest beta of XBMC in the settings under screen you can set which screen XBMC opens into.
On your computer make sure the screens settings are not set to mirrored and that your primary screen is not the screen XBMC will be on. And you should be set.
I use macs so cannot help you with screen settings on PC, somthing to do with F10 I think.
I have this setup on a Windows 7 machine. I have XBMC on my secondary display (My HDTV via DVI) and can use my machine fully on my primary display while watching whatever I want. Latest XBMC is required though as 9.04 doesn't support choosing which display XBMC is on.
That sounds just perfect
Anyone knows if mythtv also supports this?
