You need to convert them specifically for PAL tv-out, or something?

Some codecs/containers are variable fps so in those cases mplayer
doesn't say, but for the fixed-framerate ones you'll see a line like

VIDEO:  MPEG2  480x576  (aspect 2)  25.00 fps  2500.0 kbps (312.5 kbyte/s)

If you're lazy... :
$ mplayer somevideo.avi | grep -i fps
