Computer: DVBViewer Recording Service
I had a running installation of DVBViewer with the recording service on my computer. At some point in time the associated webserver switched from port 8081 to the default port 80 making it impossible to use my “normal” local Apache webserver.
During the configuration dialog I could change the port to something, say 8085, but the changed configuration was not saved – port 80 remained active.
The reason was easy to find: the configuration file “service.xml” was somehow destroyed with a lot of NUL characters. The solution was to copy an older syntactical correct version of service.xml to the configuration directory (c:/ProgramData/CMUV/DVBViewer/config)
