Refreshrate of configuration->dvb-inputs->tv-adapters->services
The refreshrate of the services-page is so annoying - damn :O
If there are plenty services, no manual changes are possible - well, nearly ;)
If you change more than one entry or happen to do your changes at a wrong time - all changes are lost and the web-if is frozen until the refreshrate-data is processed.
My box is not the fastest, but not the slowest either - might be midrange system. Network is only 100 MBit/s, but I think, management of webif should be possible even on slower systems.
I would very like the possibility to switch into manual update mode (which might be a feature request), so you can change whatever you like to change and after saving return to automatic update mode.
Anyway - I consider the current behaviour a bug!
