Hi,

I've been rendering into yuv4mpeg format and have noticed that the
aspect ratio header in the output yuv file is not properly set. My
original project is ntsc-dv in a quicktime-for-linux container with a
4:3 aspect ratio. When I render to yuv4mpeg then do: 
    cat mymovie.yuv | head -n 1 
it shows a 10/11 aspect ratio:
    YUV4MPEG2 W720 H480 F30000:1001 Ib A10:11 C420jpeg

Mplayer reports a 1.36:1 ratio using -identify. The problem with this is
that subsequent pipes to yuvdeinterlace result in black bands at the top
and bottom of the image. I also noticed the interlacing field bug in
batch rendering, but this can be fixed with a call to yuvcorrect.

Alec
