Not to keep bringing this up but is anyone having success converting RAW's to DNG's on files larger than 4GB. I have tried both RAW2DNG and RawMagic on my mac and had no success. Smaller clips than 4GB's work great.

This is my first post on this forum so i apologise if this has been answered else where but i searched and this is the only thread that came up.
I shot 15 clips of which 6 went over the 4gb mark. The card still had approximately 13gb of spaced remaining. I used Raw2DNG version 0.13 to convert the clips to DNG's. Of all the clips only the ones that whet over the 4gb mark came up with this error:
Error: This ain't a lv_rec RAW file
I have been through this process and replaced the footer for a 4.29gb file with the 8GB  footer from above and when i tried to open the DNG image sequence in After Effects i got a lot of very corrupt looking images with psychedelic colors in them.
Please help 
This is not some thing that I can reshoot as it was dolphins feeding on small fish.
