Bit of a longshot Paul but I presume you have a reader for afn in your oscam.server file? I had the same issue as you (audio but no video) but adding the following to oscam.server fixed the problem after a reboot:I'll try ,just a minute..
[reader]
label = AFN
description = AFN-EMU
protocol = emu
device = Emulator
caid = 0E00
detect = cd
group = 1
emmcache = 1,5,31,1
emu_auproviders = 0E00:000000
auprovid = 000E00
cacheex = 1
cacheex_maxhop = 1
cacheex_allow_request = 1
services = afn
Worth a try.
