Yes some very welcome additions and modifications, the latest release is running beautifully here. Although Martin says a port to Linux would be hard I think he *MIGHT* be persuaded to investigate this, and I think it could be very popular.

Works well on my laptop too
Thanks to Martin for putting in the time and effort.

Great - very good in fact - except it doesn't work properly for me as there seems no way to set the LNB volts on my ethernet connected picotuner. I can fool it into working by setting those with Rob's quicktune, but not from Opentuner itself. This setting is just not available in the source settings, whereas it is for USB connected tuners. There also seems no way to stop it apart from closing it down. Maybe I need to look at the manual again, it has been a while.

Something I have always wondered about Opentuner is how large it is. This is 188Mb as a zip and almost 470Mb when unzipped. Half of this is from including the entire libvlc for both 32bit and 64 bit systems. I wonder if Martin could trim it back a bit? All those DLLs can't be being used. I deleted the 32bit libvlc and it works fine, is 130mb smaller. I can't imagine there are that many 32 bit systems left.

The LNB voltage control works perfectly, provided that the RT5047A type DC/DC converters for the LNB voltages are used.
You can select the voltages in the "Hardware Properties" field using the right mouse button.
See the attached circuit diagram of my PicoTuner.

You have to right click on the orange bit? I had tried left clicking.. I see - hardly intuitive. Why can't you set it in the setup like all the other interfaces?
