that isnt as easy as you think, there are couple of problems
first(hardware):
tuner and diseq switch 1.1 compatibility
have discovered losing selected input problem comes after first 10-15 minutes when tuner module becomes hot
second(firmware):
autoservices scan function adds services without any checking does that caught frequency is from right sat position
and that means if Enigma* thinks you are on one sat position but on cable comes signal from another
then automaticly will be added that wrong services to wrong position
that case can happen on many reasons:
a) diseq input were changed by second receiver
b) too long cable
....
(same on Enigma1, but there you can disable that function)
third(firmware):
zaping can go wrong when some incorrect service blocking some choosen
that incorect services can be presented in services list cause:
a) GoTo second
b) some transponder on one sat position has same identificators
c) some transponder is gone or changed parameters and new one has same identificators
last(DMM):
customer care ignores theyr users problems
solution(a pain in the a**):
clean setting;
scan on cold dm800 from zero;
reboot from menu before any channel zap;
take /etc/enigma2/lamedb and save it as backup file;
replace lamedb file when it corrupted
and one thing which i havent tested for long period, but looks like it helps:
i have added diseq switch 4x1(protocol 1.0) between dm800 and diseq switch 10x1(protocol 1.1)
and changed setings like cascade trough BA port of 4x1
