The demodulator requires a firmware file that must be uploaded by the driver: dvb-demod-m88ds3103.fw
The file is part of OpenELEC dvb-firmware package: download

- The LED indicator does not work as described in the manufacturer documentation. The LED will signal green, regardless of the power supply of the LNB. So even if your LNB or multi-switch needs a power feed to work and you don't have the external power supply connected, the PCTVs LED will signal green. No reception is possible in this situation.
- At least in some cases the PCTV 461e will not supply the LNB with the feeding power. The forum post  describes the problem and gives a working solution: A fully connected (USB and external power source) PCTV 461e does not supply any operating power to the LNB/Multi-switch. So no reception is possible. The following workaround seems to work: Install the manufacturer supplied TV-reception program under windows and search for a channel. Watch it for a few seconds. Now you can disconnect it from Windows and connect it to your Linux installation. This worked for the forum poster and for me.
