ttvdb.py: error: no such option: - 

the log excerpt shows a usage of minus that will not lead to a good match, but there are others where the minus really is part of the title

The first character of the subtitle is '-', which is not being handled properly by the command line parser in ttvdb.py.

I'm moving this elsewhere, as there is really very little sensible way to make this work. I don't know of any instance where having a dash as the first character in a subtitle would be correct, so it would be better to handle this as sanitization when initially importing the guide data.
