Enigma2 should should have 1080p@50Hz

Enigma2 should should have 1080p@50Hz or 60Hz , with 24.25.30 Hz we see a jerky or jumpy motion with most of HDTV , but I don't know why they set Enigma2 with 24,25,30Hz !!?

Why no one gives any idea !!! the new Enigma2 (0.9.5 Nightly build) has the same problem with 1080p , and not any idea what the hell is the problem !!!!!!
