Hi
OGG THEORA does work mostly when the ratio is scaled with an even value ( 100%, 80%, 20%,....) but
fails initializing with unven counts here ( 25%, 33%, ..) with some exeptions ( 88% fails too ).
This could be due rounding errors for resulting width/high or another yet unknown limitation
in codec. Should be worked around somehow.
Failure verified for OSX 10.5/6 64bit by me and Damien atm..
To test: just render an animation example 640 x 480 with downscaled output 25%.
Cheers..Jens

From lib theora documentation:
http://www.theora.org/doc/libtheora-1.0/structth__info.html
"Encoded Theora frames must be a multiple of 16 in size; this is what the frame_width and frame_height members represent. To handle arbitrary picture sizes, a crop rectangle is specified in the pic_x, pic_y, pic_width and pic_height members."
So this gives a solution for a workaround...

Based on the comment from Damien I'm rejecting this report. Something that definitely needs to be documented well, though.
