MPlayer2 seek does not work for MPEG1 program stream files

Iím working with the new MPlayer2.exe under windows in slave mode.
I want to do a precise seek in a MPEG1 program stream files(m2v video with mp2 audio), using the new MPlayer2.exe precise seek command, seek <value> [type] [hr-seek].

The way I used the command is,
seek <value> [type] [hr-seek]
type = 2 is a seek to an absolute position of <value> seconds.
hr-seek = 1 means force precise seek if possible.
In my C code I gave the command with the <value> for the time position as a double, calculated for the required frame. ("seek %f 2 1", fTime).

This works for MPEG2 program stream files(m2v video with mp2 audio), and other types like .AVI.
But for MPEG1 program stream files it jumps only to the key frames and not to the exact frame as expected.

Can someone please tell me why it does not work for MPEG1 files? Is there anyway to sort this out?
I have uploaded MPEG1 program stream sample files at,
