Use register example with video player

Thank you for replying RokuPatrick.

I need all my content to be Linked to a user account.

Here is the function in videoplayer example where i call the doRegistration() method..

Function showHomeScreen(screen) As Integer

    if validateParam(screen, "roPosterScreen", "showHomeScreen") = false return -1

    initCategoryList()
    screen.SetContentList(m.Categories.Kids)
    screen.SetFocusedListItem(3)
    screen.Show()

    while true
        msg = wait(0, screen.GetMessagePort())
        if type(msg) = "roPosterScreenEvent" then
            print "showHomeScreen | msg = "; msg.GetMessage() " | index = "; msg.GetIndex()
            if msg.isListFocused() then
                print "list focused | index = "; msg.GetIndex(); " | category = "; m.curCategory
            else if msg.isListItemSelected() then
                print "list item selected | index = "; msg.GetIndex()
				regIndex = doRegistration()
				if regIndex = 0 then
					print "We are registered. Proceed"
					kid = m.Categories.Kids[msg.GetIndex()]
					if kid.type = "special_category" then
						displaySpecialCategoryScreen()
					else
						displayCategoryPosterScreen(kid)
					end if
				end if
            else if msg.isScreenClosed() then
                return -1
            end if
        end If
    end while

    return 0

End Function
