Assuming "saved as mpeg" means that you are dumping the transport stream from
DVB into a file, mplayer will show the "presentation time stamp" (pts) from the
transport stream as current position (which is not what you want). You have to
remux your stream into mpeg (an mpeg program stream) to change this behaviour.

If you already did remux the transport stream into an mpeg file (a program
stream) and mplayer does not show correct length and position, this would be a
bug and complete, uncut output of MPlayer (and probably a sample) are needed.

To remux, use either ProjectX (and mplex) or 
ffmpeg -i yourfile -acodec copy -vcodec copy test.mpg

If we are talking about H264, remuxing is currently difficult.
