What me some Sony-atypical but noticed:
The buttons on the player acting as already criticized, very cheap!
The switch from DVD to USB I find a bit awkward.
When playing AVI files from DVD I had also stuttering. These same files from USB stick running properly.
No Open / Close on the remote control
Good:
A remote control can also operate my Sony TV! AV channel and volume without changing another FB! That was important to me!
Picture and sound quality!
Conclusion: Good DVD player with a few small, Sony-atypical defects. Who does not want to use Blu-Ray can access here safely
