This depends on how far ahead the read request are and how full the
cache is.
If you made the cache large enough (e.g. larger than the file),
even seeking back should not send a request, otherwise that's a bug.

I don't think MPlayer supports an index for seeking, so it just does a
kind of binary search for the right position.
When seeking backwards you probably mean to a part that was already
played - in that case it put the position in the index and knows exactly
where to go.
