#911: ffplay can't handle timecodes of WMV2 video correctly

-------------------------------------+-------------------------------------
When using ffplay to play WMV2 video and using -ss seconds parameter to
set starting play time, but ffplay can't position the specified time to
start playing. For example, when I use 'ffplay -ss 9' command to play the
video, ffplay always starts playing from the begining and does't play it
from 9s.
