When checking the available space on a filesystem, different results are 
returned--even for the same filesystem--when using different mount types 
(i.e. local vs network mount).  Therefore, to do its best to determine 
if a filesystem is the same as an existing filesystem, MythTV has a 
"slop" factor.  Your system is likely just returning a value that's 
outside this range.  (Though the results should be the same in the 
frontend/backend or MythWeb as only the backend(s) makes the 
determination (and it provides the info to MythWeb).)

I think Myth is currently using about 2MB slop, but feel free to look it 
up in the code.
