Do you have _any_ programming experience (maybe with C)?
It doesn't take too much to use an editor and insert the above line,
recompile and do a test run. Don't let yourself be irritated by the C++
stuff. It's not that far away from C ;-)

Start with the functions RemoveDeletedRecordings() and AssertFreeDiskSpace()
(both in VDR/recording.c) and check whether they really do return.

Then continue to cRecordControl::Process() and so on. Do this until you
insert the line at a point where the program should pass through, but crashes
before it can do so. It may be a tedious task to track down the place where
the actual problem occurs, but that's what debugging is about ;-)
