I've taken measurements of power consumption on my vdr boxes. Both have had a single DVB-T budget card and playback is via the VOMP plugin. The present machine is a 2.3 GHz Athlon X2 64-bit. It idles at 42w, starting and stopping vdr has no measurable effect so I leave it running. The previous one used a 32-bit Athlon mobile CPU in a desktop motherboard. That machine idled at 62w (less efficient power supply and higher-spec graphics card). With vdr running the CPU temperature increased by 1 degree C and power consumption increased about 1 watt. It would be possible to save a few more watts if the DVB card could be completely powered off (my new machine needs only 38w without the card installed) but AFAIK that's not possible for PCI. A better bet for a 'green' vdr is careful choice of components. -- Dave _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
