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

[Raymond Wagner]

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.

Moving this to mythfilldatabase assumes that this could only affect recordings and not videos. Besides which there are multiple ways guide data can be imported (xmltv, sd and EIT to name just the ones we support). I'd imagine there are many cases where a hyphen legitimately forms part of a title or subtitle.

Having mythvideo or the scripts escape such characters before doing lookups seems like the most sensible way forward.

[Raymond Wagner]

The problem wasn't that the title or subtitle contained a dash, but that the first character of the subtitle was a dash. Arguably, that should never happen, and indicates bad data coming from mythfilldatabase or the EIT scanner.
