It's VERY confusing when you use the term "LDS record." What are you referring to? The IGI? Records indexed on the new FamilySearch website? Images of records on the new FamilySearch website? FHL microfilm of original records?
When you say "the LDS website doesn't have birth records for Münchweiler" are you referring to the FHL catalog? I suppose I could look it up, but I'm not going to. It would be better if you more clearly explained what you mean by "LDS records" in every place you have used that term.
