avrdude + avrstudio / stk500 / ATMEGA162 - programming problems

Firstly, Thanks all for your help so far, unfortunately I'm not much
further but the help is appreciated.
Secondary, I'm not sure that this topic should be in the avrdude mailing
list due to the fact that I have problems programming the part with
AVRStudio as well. Please give advice which list (or both) is most
appropriate.

I received an email suggesting I try the following

I'm using the clock source from the master controller on the stk500. The
XTAL1 jumper is connected which means that I am using the stk500
internal clock system and also OSCSEL is connected to 1+2. If I look at
some debug o/p from avrdude it states that the Osc is 3.686 MHz. The SCK
used is 1.1uS. I don't know how to check this in AVRStudio however.

I updated AVRStudio (to 4.10) and this automatically upgraded the
firmware for the STK500 to 1.18. Unfortunately I got the same results.

After much searching I found this thread
http://www.mikrocontroller.net/forum/read-1-51373.html, the original
author seemed to have similar problems to me. The last post was on the
17th so I'm not sure if he solved his problem or not. I'll try posting
in there as well though.

My problems now though are the following:

avrdude done.  Thank you.

Using AVRStudio

////
Programming Mode = ISP

Debug window: 
Detecting on 'Auto'...
STK500 found on COM1:
Getting revisions.. HW: 0x02, SW Major: 0x01, SW Minor: 0x12 .. OK

Clicking on PROGRAM, I received a generic error pop up window stating
problems occurred and check debug window:

Debug window:
Reading FLASH input file.. OK
Setting device parameters, parallel programming mode ..OK
Entering programming mode.. OK
Programming FLASH using block mode..       FAILED!
Leaving programming mode.. FAILED!

Reading the signature now I only receive 0xFF 0xFF 0xFF. I don't seem to
have the behaviour from before when random bytes are read.

Debug window:
Setting device parameters, parallel programming mode ..OK
Entering programming mode.. OK
Reading signature.. 0xFF 0xFF 0xFF .. OK
Leaving programming mode.. OK

The following lock bits are set:

Mode 1,
Application Protection Mode 1,
Bootloader protection Mode 1

If I click on read in this tab then the debug windows states that the
read was successfully but I'm suspicious of this.

In the Fuses tab:

Brown out disabled,
Boot flash section size = 128words
Ext Crystal Osc: Start-up time = 16K CK + 65ms.

If I play about trying to change the clock settings ten I receive the
following:

Setting device parameters, parallel programming mode ..OK
Entering programming mode.. OK
Programming fuses.. FAILED!
Leaving programming mode.. FAILED!


More ideas / suggestions welcomed.

One last question. Has anybody successfully programmed a 162 part USING
the stk500?

Thanks
Steve
