Quite difficult, on some Disk's the playback stalls at copyright instead of playing the copyright-message and goto menu. On my Linux-PC I can press the menu-key and everything's fine.
You are lucky to be able to play all copyright protected DVD's, with DVD menu or not. I bought a drive, too, but gave it back, because it didn't played all my DVD's. Maybe I'll give it another shot later. That's why I'm interested in this thread.
Generally, DVD support on Linux (including standard Linux PC) is not perfect. DVD-CSS has been decrypted, right, but we still have issues at some DVD menu screens. I think it's a bad DVD-CSS implementation, not an LE problem, which just uses the DVD-CSS library.
Pressing the menu key is a trick to side-track DVD-CSS bugs. Yes, we should have this option on LE, too.
