[QUOTE="mm1352000, post: 690815, member: 82144"] Hi there I am guessing that the conflicting channels are on transponders with opposite polarities. Vertical transponders (eg. SBS, Optus D2) are selected with 13V. Horizontal transponders (eg. Sky, Freeview) are selected with 18V. Your all-ports-power-pass splitter will pass the highest voltage to the LNB, so if you are trying to watch a channel on a horizontal transponder using the Hauppauge while trying to watch a channel on a vertical transponder using the Twinhan, the Hauppauge tuner will "win" and both tuners will only be able to tune to channels from horizontal transponders... Now, in making that answer I have made quite a number of assumptions. If I'm right then you need something like [URL="http://www.freeviewshop.co.nz/input-output-satellite-multiswitch-p-51.html"]this[/URL]. It will allow you to watch horizontal channels from one satellite at the same time as vertical channels from another.
