I Use TNAP4.2 an American image made especially for Edision MIO4K (+) and for the blindscan
I only use my receiver for the Dx, so everything else is no problem for meTNAP is a good image for an FTA receiver. It is fast, has a good blind scan and is actively supported.
However, it can be a little tricky to setup for things like oscam as some of the relevant functionality has been removed.
If I remember correctly, I had to FTP some files, possibly library files into the E2 system to get oscam to work?
