My as a "demo" Purchased player let a only once for a few seconds an original DVD. Then nothing more. The carriage motor was ridiculous noises, the main engine accelerated rapidly and partly also stopped loud again. No, it was no transport safety device available - it was the players. If that happens in a demo with no major Mileage I am more than critical as long as these Devices normally run at the customer. Conclusion: The player has top data but poor quality
