I haven't tried mplayer from SVN, but the video playing too fast issue
is your audio codec.  mplayer (and gstreamer, iirc) seem to set the
frame rate based on the audio.  Generally, what I have seen is that
people with ATI/AMD (radeon) video cards with HDMI ports end up with the
HDMI port as dsp0.  If you aren't running the radeonhd driver with the
AUDIO option set, the codec isn't initialized properly and so the video
plays too fast.  To correct this issue, usually all you need to do is
set the sysctl hw.snd.default_unit to the correct pcm device. Basically,
if you have the following:

balrog% cat /dev/sndstat 
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA ATI R6xx HDMI PCM #0 HDMI> at cad 0 nid 1 on hdac0 kld
snd_hda [MPSAFE] (1p:1v/0r:0v channels simplex)
pcm1: <HDA Analog Devices AD1989B PCM #0 Analog> at cad 0 nid 1 on hdac1
kld snd_hda [MPSAFE] (1p:4v/1r:2v channels duplex default)
pcm2: <HDA Analog Devices AD1989B PCM #1 Analog> at cad 0 nid 1 on hdac1
kld snd_hda [MPSAFE] (1p:1v/0r:0v channels simplex)
pcm3: <HDA Analog Devices AD1989B PCM #2 Digital> at cad 0 nid 1 on
hdac1 kld snd_hda [MPSAFE] (1p:1v/0r:0v channels simplex)
pcm4: <HDA Analog Devices AD1989B PCM #3 Digital> at cad 0 nid 1 on
hdac1 kld snd_hda [MPSAFE] (1p:1v/0r:0v channels simplex)

Setting "sysctl hw.snd.default_unit=1" will choose the primary analog
pcm for audio output and mplayer will work fine.
