Hello! From a long time (since 2010) i was wrote here bugreport but i lose my registration, this is new one.

In VLC is checked option "inhibit power manager" I tryied some ideas from IRC channel but doesnt help or doesnt get any information.

"timeout: 600" is likely why you're seeing the blanking. Have you tried manipulating the Blank settings in the Display tab of xfce4-power-manager-settings? This should change the timeout and you can also pull the slider to the absolute left, which should inhibit blanking. Generally speaking, enabling the presentation mode (via the power manager panel plugin) should also work for your usecase.

No effect! http://s016.radikal.ru/i334/1505/4d/c4c71ab93a83.png
When manipulating the Blanking setting in the tab you show in your screenshot, does "xset q | grep timeout" show changed values? (E.g. when setting blanking in xfce4-power-manager to 5 minutes, the value in the terminal should be 300)

Right, so it seems at least that part works fine. Are the values remembered correctly when you restart the session?

I'm not sure what you're expecting. In case you expect xfce4-power-manager to actively detect that vlc is running and playing something back and consequently inhibit the screensaver, then I'm sorry to say but that's impossible. Vlc can however inhibit the screensaver on its own (e.g. via xdg-screensaver). From what I can see, xfce4-power-manager behaves as expected, i.e. with "Presentation mode" activated the screen doesn't blank and with the Blanking timeout set to 0 it doesn't blank at all.

I reported this in 2010 pretty same..
As I said, xfce4-power-manager cannot determine when to inhibit the screensaver and when not to, that is up to the media-player (in your case VLC). We implemented screensaver-inhibition in Parole, so this works fine there. Since we know that this is a problem with some media-players we implemented the Presentation mode as a workaround for this problem, so you can easily and quickly flip a single switch to inhibit the screensaver. Overall things haven't changed since 2010 unfortunately, it's still up to VLC to inhibit the screensaver because there are no general standards for screensaver-interaction...
