There really is no such think as a DVD player that will play all discs perfectly. Just try to stay with a name brand player and you should have minimal problems.
I've had excellent luck with the Toshiba brand. I have a cheap Toshiba, and it seems to play everything, even stuff our other (more expensive) players spit out.
I have a cheapie Magnavox that is a dual DVD & VHS player Never had an issue w/ any of Cathes stuff new or old..(*knocking on wood). I think you still use VHS too Latrese.... LOVE mine
