ArtNet to PixelMapping problems

Hey There,
i try to convert ArtNet data into a PixelMapping Video. Yeah, this direktion!
Im Sending around 100 Universes off information (i try it with ArtNet and SACN). My problem is to grab more than 1 Universe at the same time from the DMXIn Node.
When i fill the Table with the informations Net/Subnet/Universe the DMXIn Chop show me the changing Values but the Select Chop cant read it anymore.

Here i try to Use 1 DMXIn Chop Per Univers. With this Amount of Nodes it alreade start to flicker, so i is no possible way. I think the multiple DMXIn are running out of sync.

Maybe you have an idea to got my result.
Thanks
