Subtitles integration issues

[Siliam]

Some overlapping programs makes any alignment impossible (e.g a program starts at 19/05 at 23:08 but ends on 19/05 at 00:13). Should check whether the problem only concerns programs airing through midnight.

Some programs have different subtitles for the same timestamps / periods (with different entries describing the same program)

@Siliam Thanks for filing this bug! The description is however to short to grasp the problem. Please, add more comments with concrete examples of duplicate programs or programs spanning 2 days.
