I don't know the proper drawing methods for a real schematic, so I'll try to do it verbally... Cable from the wall goes to an rf converter box, which I have to use because my dvr/cable box won't pick up the signal coming from the ps3 on its aux inputs. So I have the cable from the wall and the ps3 red, white and yellow going into the rf box. RF box puts the ps3 signal onto channel 3 or 4. Co-ax out from the rf box to the dvr. Stereo out from the dvr to the stereo amp. Co-ax out from the dvr to the tv. The noise/humming only happens when the signal is set to the ps3 on channel 3 or 4. Regular cable sounds fine. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-community/message.cfm/messageid:282054 Subscription: http://www.houseoffusion.com/groups/cf-community/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.5
