We still have a problem with directory names ending in a . (dot), which happens when you have a unique directory for the title and the title is longer than normal. In that case, the title will be truncated and ends in ...
Windows will not open directories that end in a .

Ok. I'll check this and prepare new PR.

According to http://support2.microsoft.com/kb/320081/en

Cause 6: The file name includes an invalid name in the Win32 name space
You may not be able to delete a file if the file name includes an invalid name (for example, the file name has a trailing space or a trailing period or the file name is made up of a space only).

So trailing spaces and trailing dots should be removed (or replaced??)

obviously, that applies only to directory names because recording files end in .ts or .mkv.
replace trailing dots only when 'remove unsafe characters' has been selected.
trimming blanks is a good idea, any time.
