Mplayer perfectly supports PAL, actually, mplayer does not care, because
on the level of decoding and playing streams, the only difference between
NTSC and PAL is the frame rate and the frame size, the main difference between
PAL and NTSC is how the colour signal is modulated onto the carrier. By the
way, most of Europe uses PAL, the rest using SECAM. NTSC is mainly used in the
US and in Japan.

Your problem is called interlacing, try something like -vop lbb, look it up
in the documentation under deinterlacing.
