let's have a look on the following situation.

I have full HD TV set, which of course can upscale. TV
My xorg.conf has default mode - 1080p

can be 2 situation

With vdr and vdr-xine I'm watching SD 576i channels and after that I switch to 
HD 1080i channel.

Does graphic card do upscale in first variant (with SD channel) ?
