known problem.
I think it needs a certain workaround in player to solve it. Even Zoomplayer as a reference for the least bugs and also original media player 6.4 aka mplayer2 do not perform this. As an interpretation I assume that
rewind is not supported by the DirectShowFilter from Tobias Waldvogel (
http://tobias.everwicked.com).
He is currently working on a completely reconstructed set of DSF and has joined the OGG media team at
http://www.xiph.org to help them implement their OGG theora=video codec into DirectShow.
Let's wait a while... :?
