x264 on Ubuntu video bad/corrupted

I am trying to use command line x264 to produce a blu-ray compatible file
for use in Adobe Encore. For the source file I've tried both ProRes and
mpeg2, both 1080p24. Both files import into Encore fine (no transcoding
needed which is great) but the ProRes version is pink and grey "static"
and the mpeg2 is just a bunch of green/black lines. The exact same files
and the exact same commands on my Win7 PC come out fine. I'm only doing a
10 sec sample of the complete 90min movie. I'd love for it to work on
Ubuntu cause it is running a new i7 haswell that encodes MUCH quicker than
my PC (many hours difference in encoding time)
Ubuntu 13.04

"bt709" --sar 1:1 -o output.264 --input-res 1920x1080 sample.mov
(if it would work I'd be doing two pass encoding)
I am able to encode the sample file with ffmpeg to h264 (if that helps).
Any help/insight would be appreciated.
thanks
