yes, my PCI Geforce 8400 card on GPU G98 can do 10...@50 but with the simplest
bob deinterlacing only. I prefer to use
more advanced deinterlacing algorithm - temporal_spatial or temporal. But with
them I have jerky video

Yes, exactly what I want to try, But I couldn't run properly 10...@50 - even in
xorg.log I have the report about validated
10...@50 mode - my LCD TV Philips 9703PFL reported about 1080p source from hdmi

yes it's possible
Chapter 19. Programming Modes
The NVIDIA Accelerated Linux Graphics Driver supports all standard VGA and VESA
modes, as well as most user-written custom
mode lines; double-scan modes are supported on all hardware. Interlaced modes
are supported on all GeForce FX/Quadro FX
and newer GPUs, and certain older GPUs; the X log file will contain a message
"Interlaced video modes are supported on
this GPU" if interlaced modes are supported.
Note that when validating interlaced mode timings, VertRefresh specifies the
field rate, rather than the frame rate. For example, the following modeline has
a vertical refresh rate of 87 Hz:
# 1024x768i @ 87Hz (industry standard)
ModeLine "1024x768" 44.9 1024 1032 1208 1264 768 768 776 817 +hsync +vsync
