For those on OpenAtv 7.4 who may have some problems using oscam-11748-800, here is what i have found and the "solution" (for my own problem),
hoping it may work for someone else
Using oscam-11734-799-armv7ve-libusb-aio for Vu+ 4K SE on OpenAtv 7.4 with initial conf given on first page, working flawless.
Updating to oscam-11748-800-armv7ve-libusb-aio, CWs for SkyUK & SkyDe was shown on log but no clearing.
After some reviews and tests on this post and another one, i finally made it working again (btw clearing) by adding on the Source Stream User (option i dont remember so far used before ??? Samur may answer about that) the name i use on my machine, a reboot and it is clearing again on screen.
Regards
