Streaming scheduled TV shows according to a CSV playlist
I'd start with a few specific points for the code style.


Consistent naming. You are mixing snake_case and camelCase. Check the section on naming conventions.
Whitespaces around keyword arguments is advised against.
Try to use str.format() or str % () modes to insert variables into strings, preferring the .format over % style. If you do decide to switch to python 3.6+ (as commented), you also have f"" (format-type strings).
Order your imports in the following suggested order:


Standard library imports.
Related third party imports.
Local application/library specific imports.





Now, to some changes you can do for optimisations, maintainability and portability.


Your entire cron.py is redundant. Since everything it does depends only on the tvshow.py, switch to only using that file. Place the code currently in cron.py inside the if __name__ == "__main__" block.
You're trying to import config twice.

import config
import csv
import config

You can have a class TVSchedule(r), which reads the config file when initialising, and sets up the file_name, time, app_path beforehand.
The performance of scanFileForTime and getFileContent will get better if the latter yields the rows :)
Make use of .extend method; so that the following:

for item in config.appArguments:
    arguments.append(item)


becomes

arguments.extend(config.appArguments)
