Ok, this may be simple to those who understand computers better than me, but my challenge was to take my Imovie clips from my Mac, move to an external hard drive and watch on the Oppo.
Here is how i did it:
1) Buy Paragon NTFS for Mac OS x. Install on mac, and it fixes the communication problems between the Mac system and NTFS, providing full read and write access to Windows NTFS partitions under Mac OS X.
2) Select clips from your Imovie and make a Project.
3) Finalize project.
4) Go to Share->Export using Quicktime . save as a .mov file, Under options set video compression to H.264 and sound format to AAC.
Then find it in your Movies file on the Mac.
5)Copy to your external hard drive( i am using a Iomega 1 TB drive, plug into oppo and enjoy
