Just in case someone needs to know this information. Please note that I am not a programmer. I am just hacking away.
Most of the credit for the hack goes to the person in the forum mentioned below for finding the Mac NFS behavior. http://forums.creativecow.net/thread/8/975362
The changes done seem to work well.
I am dissapointed that Apple made changes to NFS to a point that we have to use an Apple NFS. I thought that NFS is open. Anyway with these changes, a Linux server can be used.
Anyway this problem only happens from with in the video editing application, Final Cut Pro, an Apple product. I hope someday a good video editing application comes to Linux. I am willing to pay for Linux video editing application. It must be good that is.
Anyway here is the patch done.
