It may not be the same issue but when I was encoding to x264 with CVS
from a couple of months back I found that the video was delayed by
frame_duration*max_bframes.  I don't know if it was an encoding or
decoding issue and I wound up hacking around it by using
raw[audio|video], muxing to matroska and setting an audio delay in
matroska.  I was also using Vorbis audio instead of faac because I never
got faac working on windows and the files where destined for PC only
playback anyway.
