Hey Bill,
The easiest way I know of, is just to do a save set recover with the -a option and the path and file you want recovered.
For example:
recover -s backup server -Sssid -a /path/file_name_to_recover
It takes a bit longer, as it has to go through the all the tapes in the save set, until it finds your file, but it works.
Good luck!!
