An other reason could be that asf demuxer in mplayer seek the file based on
a "packetrate" instead of the index, and the packetrate is calculated by:
here the max_bitrate is the uncompressed rate based on the unofficial asf
spec, so generally packetrate will be larger than the real rate, that mean
you usually seek more forward than you expected.
