For future bug reports: Please always add a command line together with complete, uncut console output

Seeking works, but not as expected:
With ffplay and mplayer -demuxer lavf, the only reachable times are (0:00 and) 0:15 and 3:22 (except if the first forward seek is later than 16 seconds into the stream).
mplayer -demuxer asf seeks fine, there are enough I-frames in the stream.
