I can reproduce the problem with the default libavformat demuxer:

mplayer -demuxer lavfpref vc1_in_wmv.wmv

But not with the internal asf demuxer:

mplayer -demuxer asf vc1_in_wmv.wmv

Interestingly, avplay does not have any problems with seeking:

avplay vc1_in_wmv.wmv

This doesn't mean that libavformat was bugfree, this may as well
indicate a problem in the way how mplayer2 drives libavformat.

Uoti, can you have a look at this? Thanks!
