Monty,
One other issue: after installing your updates from git:

I tried to render out (shift-R) the video of my test project as a
YUV4MPEG stream using the following pipe:
ffmpeg -f yuv4mpegpipe -i - -y -target dvd -f mpeg2video %

The render proceeds normally (ie, I see no major errors):
  libavutil     50. 3. 0 / 50. 3. 0
  libavcodec    52.37. 1 / 52.37. 1
  libavformat   52.39. 2 / 52.39. 2
  libavdevice   52. 2. 0 / 52. 2. 0
  libavfilter    1. 4. 1 /  1. 4. 1
  libswscale     0. 7. 1 /  0. 7. 1
  libpostproc   51. 2. 0 / 51. 2. 0

But the file output cannot be played in ffplay or mplayer.  I get
gobbledeegook.

I confirmed that this is an error with your additions, as I rolled back
to my generic CinCV build and was able to do the YUV4MPEG pipe and
render successfully.
