Common Communication issue between ArduPilot V2 and FTDI

hey im having this same problem wih this sync issues. there is so many people with the same problem, im beginning to think it's a bug in the hardware or code.

avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51.

if this is such a common issue, someone must have thought of a simple way to work around this.

i followed everything on the manual and everything! please let me know what you did to fix it. im running vista 32-bit, and arduino 2.7.1. please take a look at my youtube video to compare your similar issue. and please make suggestions of what u did, or would do. thanx

here the video of it

Cooper, this is the #1 issue for anyone working with Arduino projects of any sort (not just ours), and it derives from the FTDI interface and drivers, which are complex. It is almost invariably due to a problem in your setup (it has nothing to do with the code, and rarely is due to the hardware). Can you confirm that you have checked EVERY ONE of these steps, from the manual?
