protocol error, expect=0x14, resp=0x50 - this part of the error message says that the configuration is expecting a different chip, or version of the chip. The chips have a couple "signature bytes" that AVRDudue checks to see if the correct chip is connected and the signature isn't correct. May not be a problem - ATMega328 and ATMEGA328P do this.What system are you using this on, and how comfortable are you playing around with a DOS prompt?
As I said previously, I'm trying to burn the bootloader on an ATmega8 using an Arduino Duemilanove w/ ATmega328 as ISP, using Arduino 1.0.1 in a Windows 7 64-bit system. And I am pretty confortable with the command line, that's not a problem.
