I found a bug in this patch, which caused VDR to crash whenever a
channel was selected that had multiple Apids, but none of them in the
preferred language. It seems that the PrefferedApid variable was not
being initialised in this case.

I fixed it by adding:

PrefferedApid=&apids[0];

To the top of the cChannel::SetPrefferedAlang() function in channels.s 
and removing the 'else' chunk, so that this variable always gets 
initialised with something.

Attached is the revised patch, with a new version number. I've also been
pedantic and corrected the spelling of 'preferred' throughout. :)
