Media Composer 7 not importing Cineform correctly
 

After using HDLink to create MOV files (Nikon D5100 1080p24 source) importing into a 1080p24 Media Composer project as DNxHD 175x yields a static filled image.

Linking via AMA works fine, but transcoding from AMA to DNxHD 175X yields the same static filled image.

If I directly import the D5100 media or link then transcode all works fine.

Any suggestions on how to correctly import the 10-bit/4:2:2 cineform mov into MC7?

48HFP is 3 days away...

Thanks in advance.
