if you disabled full gpu scaling , how upscaling will work really ? what and how will upscale SD video to 1080p ?
This setting is only useful if your display device can't scale on its own or the scaling is worse quality. If you enable it the card will always output native resolution at native refresh.
If disabled the gpu will not touch the mode and output whatever you tell it to, in which case the display itself will have to scale the mode as needed.
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) ?

Yes (I thought I already told you that). And in the second case it will deinterlace. Afaik vdr-xine cannot switch the display resolution/frequency to match the input signal.

Sorry to jump in on this, but I wonder if people could suggest what the settings should be in xineliboutput plugins options?
I have just upped my card from an 8400 to an N210 with 512MB ram in order to get 1080i/60hz interlacing working. It's an improvement, but I think I still have somewhere to go.
I am using a Eurospec TV although am trying to use it at 60hz (I moved to the US from Italy) via a DVI to HDMI cable. I have two modelines, which I switch by my remote using the xrandr command, 720p60 looks better, but I think I should using 1080i
I have two ATSC card which show 720p60 and 1080i60 and a Hauppuage PVR HD and the pvrinput plugin, this I use to show HD content from a cable box. That I can select to either 1080i or 720p. Most of the content is originally broadcast in 1080i.
I am using
ModeLine "1920x1080i60" 74.18 1920 2008 2052 2200 1080 1084 1094 1124 +HSync +VSync Interlace and Modeline "1280x720_60" 74.48 1280 1336 1472 1664 720 721 724 746 -HSync +Vsync
X won't display the correct resolution by default, as my edid is messed up on my TV.
What deinterlacing options should I use on the plugin? Bob? TVTime then scaler Bob? Judder correct etc etc?
Most SD stuff here is badly done 4:3, with stations like BBC America adding black bars to the top and bottom, so I get a square in the middle of the TV. Xineliboutput can zoom this quite well, but after a while the whole picture judders until I kill vdr-sxfe and reload it.
Do I need FFMpeg to work alongside it or will that kill vdpau?
Thanks..

The difference can be extremely hard to see depending on the source material, viewing distance and display size.

If the picture is first deinterlaced on the pc and then output (re)interlaced and the tv deinterlaces again I'd expect some massive quality loss from this pointlessness.
If the tv won't accept 1920x1080p60 then you're probably better off using the vdpau deinterlacer (--post tvtime:method=use_vo_driver) and 1280x720p60 mode.
