Query: A poorly designed, unreliable DVD player

I've had this player for about six months. About 15% of the DVDs that I own have at least one feature that can crash this player, when that happens the only way to reboot it is to hit the switch disk button, none of the other buttons will work. The remote control design is pathetic, half of the buttons are hidden by a cover, and are virtually inaccessable. The skip and fast forward functions are combined on a single key, to fast-forward you must hold down the skip button for several seconds, if you don't hold it down long enough it skips to the next scene. The skip backwards function doesn't work, it can only return to the start of a scene, not an earlier one. So if you accidently skip to the next scene you must restart the movie from the beginning.
