My guess would be
code for the right motor is reverse of what it should be. If it is servo powered, then the left side may be 75 - 225 (reverse - forward) and the right should then be 225 - 75 (reverse - forward).

ok?
but that will just help it drive forward or backwards. What about it tilt and pan for it front ir senors?

did a re wire
i went ahead and rewired my mr gen to this https://www.robotshop.com/letsmakerobots/files/userpics/u1533/Mr_General_ATmega8A_Wiiring_Instructions.jpg
I notice before i had forgot to put ground on pin 22 and VCC to pin 7.
now the robot will sit for a good 20 seconds when i turn it on, then start doing the same thing that my video shows.
I also want to add i never uploaded or messed with any code. I was told my chip was pre loaded.

I am not sure if it is the right cristal
my cristal only has two pins, and the ground only runs under it. It is not connected to it in anyway.

taken a few classes
I only taken a few ECET classes, I just got done with ECET 210. I got a basic idea, but i am not even sure what a crystal oscillator does. If i did I would try and test it with my multi meter.
I am also putting together a better video, I hope it helps you all help me better

you sure?
I am sure I have them hooked up right, I hate to try and remove them to flip them around to just test them.
i did notice the front left is getting low voltage, when i get time I will check the tranismitter for it.
