[mythtv] [PATCH] More improvments to guide fixup

[Torbjörn Jansson]

Here is another patch with some improvments to the dvb guide fixup.

Changes:
* Inserts year into database
* Adds new members in class Event so fixup functions can insert original air
date and credits (actors, director(s) and so on)
This also means that the Actors member in class Event is not needed. It
looks like it's never inserted in the db and i can't see how it coud work.
I haven't touched the other fixup functions since i can't test them.
* Changed EITFixUpStyle4 (comhem fixup) so it looks for actor/director and
orginal air date.

I've been running with this for a week now and it seems to work fine, but
then again i can't test how the changes affect the other guide fixup
functions.
I don't think i broke anything.


I have an idea on how to move the subtitles from the description to the
subtitle field, but this will only be posibel on some channels.
So i need some kind of list of channels (serviceid maybe?) that i can do
this on.
It woud be best if this was not hardcoded, maybe the dtv_private types table
coud be used? Any ideas?
