Comment (by froedep at googlemail.com):

 Sorry it took me so long to test your patch. I've applied it to the latest
 SVN, which builds fine. Problem is that no data is saved to the drive when
 I record anything. If I revert to SVN without the above patch I get the
 recordings as per usual.

 This is the log I get when recording something - the programme appears in
 the recorded list as normal, just no data is saved.
