[mythtv] Duplicate checking for movies does not work anymore

[Thomas Börkel]

HI!

Something must have changed in the duplicate checking for movies after 0.16.

Up to 0.16, if I set "description", it worked for movies as well as for 
series.

But in 0.18, it seems to only match the title for movies, no matter what 
I set for duplicate match criteria. Movies now seem to have some kind of 
ID. It still works OK for series.

Maybe my TV program grabber is not doing something right, but how can I 
get the old behavior back?

Thanks!

Thomas
