TVs de-interlace would matter with interlaced output but I suppose 
field/frame accurate scaled and original way interlaced e.g. 1080i 
output is not possible with Nvidia and X.org. I'm using progressive 
1080p50 output for 576i50 DVB-T/S video. Libxine handles de-interlacing, 
and Xv driver in Xorg the scaling with graphics hardware. The magic 
spell from xinelibout config is

xineliboutput.Video.DeinterlaceOptions = 
method=Greedy,cheap_mode=0,pulldown=none,framerate_mode=full,judder_correction=0,
use_progressive_frame_flag=1,chroma_filter=1,enabled=1

The result is IMHO pretty good with a 50 Hz X.org mode where 
syncronization to vertical refresh is usually close to perfect. 
De-interlacing consumes more CPU than 576i MPEG-2 video decoding.

Advertised techniques for frame rate interpolation to 100/120 Hz perhaps 
matter more for typical Blu-Ray low rate 24p videos than 50/60p 
progressive video from PC. I haven't seen those in action so I'm only 
guessing.
