Last time I worked on the DPX side of OIIO, I noticed too that the
metadata were sometimes inconsistent, but never had the time to look
deeper at the problem.
So I think it's actually a bug.

Looks like you're doing the right thing, but perhaps there is a minor
bug or two. Can you email me (privately is ok) the input file so I can
try it on my end? Should be easy to fix.

Hi guys,
2 super simple questions about DPX metadata -- my apologies if
these are obvious:
(using OIIO 1.1.2 on CentOS 6.2)
1. I notice if I simply read in a DPX with a PixelAspectRatio of 2
and write it right back out without any ops, the PixelAspectRatio
changes to 1 -- dpx:Signal also seems to be added but I'm more
concerned about data being changed than about data being added...
i.e. oiiotool my.dpx -o out.dpx
>> oiiotool -v --info my.dpx
Reading my.dpx
my.dpx : 2048 x 1556, 3 channel, uint10 dpx

oiio:BitsPerSample: 10

2. What is the proper syntax for setting metadata to a DPX file?
e.g. dpx:UserData... I tried a variation on what was in the docs
(oiiotool my.dpx --attrib "dpx:UserData" "HELLO_WORLD -o
metatest.dpx) but that didn't work.
Many thanks for your help,
Jep
