Item has been used by OS X cannot open-black Apple Road

Before copying a few video files to NTFS disk, always unusable in Mac (even chmod), no matter what kind of playback software, even to the DMG type can not be opened, the "project has been used by OS X cannot open", with the LS command to find the file attributes more than a @ flag, It is said that this property will cause a lot of problems, the suspicion is that this logo, search, using the xattr command to remove the @ property after all normal.

Xattr-l 1.RMVB, listing the file's @ attribute content, appears as follows:

a.rmvb:com.apple.finderinfo:00000000 6F 6B 4D (a)------------XX  |brokmacs........| 00000010 xx xx xx, xx, XX (|................|) at xx xx, xx  00000020

the xattr-d com.apple.FinderInfo 1.rmvb command can delete the @ property.
