Dual Video mode nVidia 5700LE

Finally broke down and got a big new TV, complete with A/V inputs. I eventually want to relegate my current PC to media storage and playback duty after I build a sim-dedicated rig this summer, so I started tinkering with things to see if I can output via S-Video to the TV from the card and still be able to use a VGA monitor with it (master plan includes a KVM switch so that I can control the "media server" from my main terminal).
Followed the directions as best I could, but got some very peculiar results:
First attempt, with VGA monitor as the master: all video content was showing up on the TV, with mouse cursor, toolbar, and icons displayed on the VGA monitor but no video.
Tried making the TV the primary display, but that caused the mouse icon to "go" to the TV, but toolbars and icons still on VGA monitor.
That's when I gave up, as it took some doing to get things back to normal (TV is set up in a loft over my workstation and the mouse cable barely reached farenough for me to see the TV).
Clearly I don't know what I'm doing, but it seems that even if I'm going dual as opposed to "clone" that the same thing should be displayed on both?
I need to use "dual" as opposed to "clone" or "span" modes so that I can set separate resolutions, etc. for TV and monitor, but I don't necessarily need anything shown on the TV besides video output... but does the above sound normal to anyone who's done this?
BTW, two other weird things happened: XP went back to the default sounds setup, and also made some random changes inthe appearence of my desktop (toolbar colors, shortcut layout).
