I've just seen a message on a German board saying that the archive at Troppau/Opava in the Northern Czech Republic has made lots of parish records (not all) available online, even without registration. Tomorrow the archive at Pilsen/Plzen will follow.http://matriky.archives.cz/
Looks quite simple:
type the Czech name of the town/village and choose the parish record.
I do not research in the Czech Republic, just wanted to let you know.
