Yep, The Lomography folks don't really want to say where their film comes from but once you look at the product it is quite obvious of its origin.

It still might be a crap shoot if your rolls are going to be OK seeing that they are indeed from Maco/Rollei, probably be a good idea to shoot and develop just one to see how it turns out, if it is good and the rest of them have the same lot number they most likely will be good as well.

Based on what we have learned so far it would seem the Maco/Rollei product is the one that is risky.....

Now it begs the question if the "yellow" film was that that sat on dealer shelves far too long......

It is a good thing the Lomography folks are looking into this "Yellow" problem, their pride in the product is really good so we can count on them for good slide film
