Thanks,

I use 50Hz refresh rate on my projector and can switch to 60Hz with
xrandr. But it is not indeed interlaced.

anyway, I tried telecine filter, what seems to do exactly same than
pullup - video plays a way too fast. I think it is because my projector
is not interlaced?

I also have tried using 1.04 speed mentioned here earlier, but it does
not work, because I have digital audio out and videos mostly use DD
sound, in that case mplayer seems to ignore speed command. With analog
audio, speed 1.04 makes playback quite smooth, but not perfect.

Any other way to correct framerate differencies?

In windows I know there is program called "reclock" and people have
reported success with it, but I wonder if there is anything similar in
Linux or mplayer?
