In practice, the answer is usually yes, but this isn't a 'recommended'
use of mencoder. :) At least be sure the codecs and encoding
parameters are the same between the files. You might get one or two
broken frames right at the merge point, but they'll normally just get
dropped when decoding so it won't be noticable. Hopefully the person
who originally split the movie wasn't so stupid as to cut it at a
point with sound.
