For EyeTV, “EyeTV Archive Location” is set in the Storage pane of EyeTV Preferences. You can change this location to other directories, even an external hard drive in Preferences. When you move a TV program (a folder that contains 4 files, minimum) from the designated storage location, EyeTV can no longer “see” the file. You can drag the program folder back to the Archive location, relaunch EyeTV, and the program will become “visible” within EyeTV again. I do not know how EyeHome interacts with EyeTV however.
