Have the receiver bought to replace a Philips DCR9001 DVB-C, the ever made restarts after a channel scan. The Opticum HD XC2 is now running with a second TV and doing there his ministry properly. He is small and unobtrusive. The initial installation takes a long time, because the receiver seemingly scans all possible Frquenzen. The sorting of the stations also takes a while because I wanted only the free channels. But you have to stop to move about 60 from about 300 possible channels upward. The menu navigation is very clear. At the Meüpunkt "update" here the testimony of Opticum: Updates will be for this receiver exclusively on our website. Updates via the cable network is not possible.
