As a simple fix, it *should* be.  As some have pointed out on -users, 
the end user could be left with no recording and no visible reason why.  
The best solution is probably a method by which the user is left with 
some kind of visible indicator of the problem while still preserving the 
deletability of the metadata and file.  Any easy fix along these lines 
might be not to insert the filename into the DB until the recording is 
really going and then adjusting the code in the necessary places that if 
the filename doesn't exist to notify the user accordingly.  I don't know 
how many places in the code manipulate the filename but it might not be 
too many...
