Quick update.

I managed to get a few print statements into the code and from what I 
can tell it looks like "host" is being set to "None" in "populate". As a 
result, nothing is added to "unfiltered".

"recs" is being populated correctly with all of the files from the 
recorded table but because "unfiltered" is empty, all of the recordings 
are listed as "Recordings with missing files".

As I mentioned earlier, I'm not a Python expert so I'm not sure if I'm 
following the logic in the code correctly. Is it normal for "host" to be 
set to "None"?

It also looks like I should be able to specify the hostname on the 
command line but every time I try to add an argument to find_orphans.py 
it fails with: Exception: Invalid hostname specified on command line.

Does anyone know what a valid command line with arguments looks like?

Thanks
Gary
