Indeed, you should not mix access to the console using Crt.Write(Ln) with access via Video.VideoBuf^. On the other hand, you can use Video.VideoBuf^ together with keyboard related functions from unit Crt (with the caveat that it would work on e.g. Win32 but not e.g. on Linux). Vice versa, you may be able to use functionality provided by unit Video for changing the console resolution (under Win32) together with Crt.Write(Ln) as long as you re-initialize the window coordinates (Crt.Window) after Video.SetVideoMode and before any Crt.Write(Ln).
