No, they're correct. Original has an ID of 4113 because it's in a
different container than the encoded one. IDs are selected by using
the -vid option. Very frequently, ts/m2ts containers have high IDs in
contrast to avi which uses low ones

This is due to default settings of x264. If you don't specify the
amount of reference frames with frameref in mencoder, the value is
picked up from the defaults of x264, and in this case it has 4
reference frames
