I doubt that this can be a problem that is due to x264. It's most
likely, IMHO, a problem of inadequate output framerate.
In order to narrow down the problem, you may want to try to encode
with another codec, like xvid or libavcodec (through ffdshow). Those
are well tested, and require less CPU power to encode as well decode;
so if you experience the same problem with them, the problem is
elsewhere.
