I am pretty sure it does not, it changes the timebase in use. In a stream
with 1/30 tb and pts values [0,1,2,3,4,5], using a 1/60 tb those pts values
would change to [0,2,4,6,8,10].

Oh, I wasn't aware of WMP having that limitation.

example to show a timing issue.
Maybe you can suggest some muxer format that supports vfr.
