Arduino Mega Blinking LED problem

Using Arduino IDE 1.x
1

Well, I've got my Arduino mega 2560 a few days now and I think it's not working 100%.
I'm a real Arduino noob, this is my first board but I have some electronics knowledge.

Well here's the problem, I transfered the "blinking led" program to my Arduino and when I use "int led = 13" then there is no problem,
the led on the board is blinking one second and one off.

But if I select another pin and I connect a resistor with a led on that pin then I get some weird blinking.
See my video: - YouTube

Is my board broken or am I doing something wrong ?

Video doesn't play. Just post your sketch (use #) and describe your wiring in detail, every connection.

Well it's a sketch from the examples:

/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.
 
  This example code is in the public domain.
 */
 
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 10;

// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);     
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);               // wait for a second
}

Video playable now ?

Resistor of 220 ohm is connected with pin 10 from there it's connected to the LED with a crocodile clip and the other leg of the led is connected to ground.

Daft question maybe, but is this a flashing led?
(looks to me like it is flashing for a second, then off for a second)

You could try connecting it to the 5V power pin via your 220 ohm resistor, just to be certain?

Well I found the problem, it's the led.
I tried 2 other leds and there are no problems with these leds.
