Hi
I'm in Australia, trying to use JRiver MC (17.0.184) with an HP Pavilion dv6 Notebook (if relevant, Win 7 x64, 8GB RAM, Radeon HD 5650 graphics) and HP USB DVB-T TV tuner. There's no problem scanning for channels or displaying a picture when running the notebook on battery power. However, as soon as I plug in the AC power adaptor, the picture disappears on all channels, even though there is still sound (the power lead and coax lead are well apart). The adaptor is the one supplied by HP with the notebook. MC17 appears to function normally in all other respects.
There is a TV picture with WMC, using either battery power or the AC adaptor.
Any ideas as to what is wrong would be much appreciated. Thanks.
