I have a few HD drives in my computer mounted as a folder on other HDD (mounted under a letter, K:). I'm not sure since what version my problem occurs, but now I can't set output file name "inside" that mounted folder name. For example, HDD1 mounted as K:, HDD2 mounted as K:\folder1, HDD3 mounted as K:\folder2. If I set output file name to K:\somefile.mkv - everything is fine. But if I try to write it to K:\folder1\somefile.mkv - I've got an error (as in Summary). A few versions ago there was no such problem.
