I do not have a VU-box but its the 2nd Google solution (1st video) in search of "VTI Image oscam.config":
https://www.youtube.com/watch?v=Rl21UvC_n-MRegarding your butler program (I do not know): as long as you get no error message I would assume config files created (via green button)
do you have an INTERNAL card in your receiver ? In this case a card for Sky Germany (that is not married to Skys oown STB or CI+modul) ??
If not perhaps a good idea to switch INTERNAL reader of ?
If you looking for a solution here on the cs-board, perhaps EXTERNAL reader might be a good idea ?? (perhaps google for the meaning of the words internal and external as well)
Only configure one "external reader" and the option "connect to Oscam server" sounds interesting. I would suggest to use Newcamd protocol with Oscam. So switch it to YES for external reader 1 sounds correct.
The Oscam WebIF is also enabled with this butler-software and if it really works you should be able to connect to the local Oscam program on your VUbox via http://<ip-of-your-stb>:83 (perhaps reboot box first after saving config
BTW: leave Oscam server options (cs378x and cccam protocol) switched OFF/NO
And once you have the Oscam web-if use the Files menü > server and replace the contend of you local settings with the server-config you got from your cs-account website
Once Oscam is running on your STB you might focus on Oscam and not on VU/VTI (if you are searching the forum or Google). Even if there might be some special options/settings related to the receiver in use most settings are the same for all receivers. As the Oscam butler screenshot looks like you have absolutely no idea how to configure perhaps try
