Malformed Packet: DMX Channels: length of contained item exceeds length of containing item

[PizzaProgram]

Hi, Great APP :-)

Sadly I can not control my special ArtNet DMX device, so I made some tests. (Changed channels count = 34)

WireShark shows errors at every 4sec output. Length = 94 byte ! If I move the slider > it creates good packages. Length = 92 byte

PS: How I do I set Universe to 1 ?
