Andrej,
you did the right placing of the various components, as far as I can recall.
XView should start whenever you:
1) Have started PSX with the Main and Boost servers up;
2) You have then started XP11, and picked the XView 744, which will activate the plugin you placed inside it's plugins folder, and not on the main XP11 plugins folder - this is the correct procedure if you just want to start XView when you pick that aircraft;
You do not need to start with any other airplane. Start with the XView 744.
I don't recall how I used to get the best results when using PSX and XP. I somehow recall that starting PSX and placing your aircraft where you want it is the best choice, and then, with PSX running and visuals required, start XP. I used to do it just before pushback, then turn XP off after initial level, and restart it back at TOD.
XP and PSX have a problem, both... They do not correctly show the proper lighting based on geographical position and date. Sometimes it's pitch dark on both XP and PSX when there's still a lot of daylight IRL... FSX and P3D do a much better job, not to mention that they have precise Moon phase and ephmeris...
You do have to at least edit the "xview.cfg" in the main XP11 folder to set your preferences ( avoid the interpolation function in XP11 ) and the IP address, which can be set to 127.0.0.1 if you're using all in the same PC.
