Deleted recordings aren't a problem--only "partially deleted 
recordings".  I'd guess you're seeing recordings that have been put into 
the Deleted recording group, and will be removed from disk at some later 
time--either after the number of days you've specified, or automatically 
when you need more space on a given file system (after all not-in-use 
Live TV recordings have been removed).

If that's the case, you can simply delete them, again, and they will be 
removed from disk (at least this is how it will work on a 
properly-functioning client system, which means that you're allowed to 
delete the Deleted recording, and the client then asks the backend to 
take care of it).

If you want them removed automatically--even when the system doesn't 
need the space (unused memory/storage is wasted memory/storage :)--you 
need to specify an appropriate value for:

Time to retain deleted recordings (days)
Determines the maximum number of days before undeleting a recording will 
become impossible. A value of zero means the recording will be 
permanently deleted between 5 and 20 minutes later. A value of minus one 
means recordings will be retained until space is required. A recording 
will always be removed before this time if the space is needed for a new 
recording.
