Arduino as ISP problem

Hi,
I have Arduino Demilanove, and after getting an Atmega168v-P10PU and other needed items, I managed to implement this tutorial:

Didn’t work!
I did everything as instructed, I have “heart beating” from LED connected and yet have this error message:

Error while burning bootloader
***failed;
avrdude: verification error, first mismatch at byte 0x0000
0x3f != 0x00
avrdude: verification error, content mismatch

Next I googled, and searched the forum, but nothing that could help me. Would you please tell me how to step forward to solve it?

edit: could it be for my Arduino is on Atmega168-20PU, but my target MCU is Atmega168v-P10PU?
