Perhaps revert-buffer-with-coding-system will do what you want (i.e.,

C-x <return> r l a t i n - 1  <return> y e s <return>

should show letters with diacritical marks properly, but it took about
20 minutes on my old dual-core k8 system).

In any case, some bisecting shows that the first problem is the line

Jedna žena – jedan vek (2011)				2011

It seems to be encoded in Windows-1250 [1] instead.  The IMDb website
[2] has also problems with this title (at least in Firefox, the
problematic letters seem to be missing somehow).
