I suggest you remove "-mc 0 -noskip -skiplimit 0" if your source is
PAL, and since you do not process sound. Those options are probably
useless for you, and may harm more than help you out.

mencoder crashed (that should not happen of course). Check your RAM to
see if it's okay (with memtest86 or smth like that, check also if your
cpu is not overclocked. Make sure also that all the libs used by
mencoder are compiled with the same version of GCC (typically, libx264
compiled with gcc4 and mencoder with gcc3.4 will crash randomly).

Otherwise, please post the exact message that got printed on screen
(here your encode seems to run with lots of the console informations
redirected to /dev/null.

Hope that helps.
