[mythtv] Mythfilldatabase & xmltv,

[Laurent ARNAL]

   Hi Everybody,

I always find that configuring TV Card in MyhTV is difficult for non US 
citizen.
What I'm usually do is:

   1/ Do a first frequency scan to find the channel.
   2/ Go to mythweb, and fill the xmltvid column by hand for each entry 
in Channel table.
   3/ Launch mythfilldatabase to fill missing informations (icons, 
programs, etc...).

Perhaps miss something somewhere, but what hurts is Step 2 because you 
don't have a link between channel frequency and xmltv informations.
The only link is the channel name that could be the same, or near the same.

What I propose is to modify void ChannelData::handleChannels.
The goal is when we are handling a channel coming from the xmltv parser, 
to verify if we don't already have an entry in the Channel table without 
xmltvid but with the same name.
If so, we can do an update of this entry, instead of doing an insert.

I Create a path for this purpose, see ticket #6531.

   Thanks,
               Laurent.
