MPlayer uses the bitrate info of mpeg header for seeking in mpeg streams.
It's not too accurate, and may be broken. In your case it seems to be
totally fscked up. Compare the bitrate printed by mplayer (it's readed from
mpeg header) to real bitrate your files are.

it's known that transcode doesn't really care in fileformat details, it only
fills the minimum to get files playable :(
