[QUOTE="gfmoore, post: 751456, member: 113222"] Hi again - hope I don't hear too many sighs! Could someone care to explain, or direct me to the relevant place, as to how the TV setup works. (I am re-requesting this as no-one might have noticed in my post on the S500) as I would still like to debug my issue. In particular what happens when parameters are sent to the tv card (esp sat) driver. What does it do, how does it recognise signals and interpret them. I assume this is something to do with "graphs". What creates these, and how can they be tested (I have graphedit, but no idea how I could work with it. In particular I would like to see what signal the driver outputs before it is sent to the lnb or graph, or is that a stupid question? Is any of this sensible?, i.e. please don't flame me for being ignorant :) Gordon [/QUOTE]
