Like I said I have never run into this likely because I don't have 1080i material it seems. But your would think that I would have the occasional interlaced movie if it was that high of a percentage.
I'd be interested in seeing a list to see what types of things are being shot in 1080i.
Lots and lots of broadcast TV is 1080i native interlaced (as opposed to 1080p carried in 1080i). Almost all major sporting events (Olympics, World Cup, Wimbledon, European Cup etc.) are shot 1080/50i or 1080/60i native. Most entertainment and HD news shows are shot 1080i native, as are some soaps and sitcoms (though 720/50p or 720/60p is used by some broadcasters instead)
Drama, some documentaries, some sitcoms and some soaps, as well as movies are 1080p.
Isn't it also true that only a CRT monitor can properly playback interlaced material as almost all modern day displays are progressive?
Yes - and no.
Modern de-interlacers are able to de-interlaced 1080/50i or 1080/60i to 1080/50p or 1080/60p pretty effectively (spatial temporal de-interlacing using vector motion tracking can deliver very good results)
As 1080/24p or 1080/25p is not suitable for high-motion capture environments - like sport, entertainment (fast crane and steadicam motion doesn't work at 24/25Hz) either broadcasters have to use 720/50p or 60p, or they have to use 1080/50i or 60i to capture 50/60Hz motion.
Many went 1080i, some went 720p. 1080/50p or 1080/60p is not being used for broadcast TV to the home (yet) - so that isn't an option.
As someone who uses XBMC (with TV Headend to watch Live TV) and also Recorded TV (SD MPEG2 576/50i and HD H264 1080/50i and 720/50p) de-interlacing is pretty important to me. nVidia VDPAU with Temporal Spatial 2x de-interlacing is pretty good. Other graphics cards don't fair so well in XBMC.
There are widespread issues with VC-1 interlaced content - but that is an FFMPEG issue AIUI - not an XBMC one.
If you only watch movies in XBMC then de-interlacing and interlaced content may not be an issue for you. It is for those of us who use XBMC to watch broadcast material.
