I share your frustration with that too - I am also researching German relatives from a small town in the former East Prussia. Absolutely none of these records have been digitised or indexed and I need to order each film individually based on town and year and scroll through the whole microfilm hoping to find information (thankfully I've been lucky, but wow it's time consuming!) Taking a photo of the image on the old microfilm reader really doesn't work well!
I'm told the LDS plan to digitise all of the films but there are thousands and it will take years. I guess they prioritise based on demand - hence why so many US and UK records are available online. I'm not sure how much demand there is for a little town in former areas of Germany.
It would be great if the FHC could have a service whereby you pay them to digitise the film you want. At the National Archives they do that - you pay them to release and scan your ancestors' files (e.g. Immigration records). That way they make money to continue their service but the documents are released on an "on demand" basis.
Good luck with your search!
