When renaming episodes of shows you have:
Show Name S Season# E Episode# Episode Title
For example
Tosh 2.0 S01E01.avi
Tosh 2.0 S01E02.avi
.
.
.
Tosh 2.0 S05E10.avi
Applying Case formatting will cause S##e## so you must setup S01E:S02E:S03E:...S10E in the exception field.
It would be nice to just put in [S]{1}[0-9]{2}[E]{1} for all possible combinations.
