right now i use process explorer to find the ports used by the process
then setup a capture filter in wireshark. Is there a way via scripting or wireshark addon
to automate this process?

Have you compared the caps of total traffic to/from the computer's IP address with caps of just the specific ports' traffic to see how much savings that really gives you?
It might be faster and easier to capture everything then filter it down to just what you want using ethereal, afterwards.

How are you ensuring the process doesn't change ports after you've setup your filters, by the way?

Microsoft Network Monitor has this ability, but the resulting file cant currently be opened in Wireshark.

Use this filter while capturing:
processname=="process.exe"

your syntax is wrong i see

udp.proc.srccmd        String        Source process name        1.2.0 to 1.2.1
or
tcp.proc.srccmd        String        Source process name        1.2.0 to 1.2.1

and you must have a very recent cut of wireshark for these display variables
to be valid

You asked for a capture filter.

tcp.proc.srccmd and upd.proc.srccmd are display filters, not capture filters.

The filter I said is for Network Monitor.

sorry about the confusion
I still say it's better to capture everything local and filter during replay. Lots of programs change their ports dynamically.
