Thanks, but that makes no difference.

Here's the format detection when I send mencoder one of these files.

libavformat file format detected.
[lavf] Video stream found, -vid 0
VIDEO:  [avc1]  1920x1080  24bpp  29.970 fps    0.0 kbps ( 0.0 kbyte/s)
[V] filefmt:44  fourcc:0x31637661  size:1920x1080  fps:29.970  ftime:=0.0334

Maybe the avc1 component needs an update. "movtoy4m" is working with two
problems. First, it's slow. 2nd, it has a dimming effect on the video which
has to be compensated for. I'm still looking into the possibility of using
qttoy4m from Mjpegtools.
