How do I do this? Pod XT pro

I would imagine that you would run your guitar into the DI box and use output one strait into the Interface and then hook the pod up to output 2(through put) and then run that into the Interface. Arm two different tracks for recording. Assign the inputs as necessary.
 
I suppose you have it sorted but...the PRO version ( since that's what is on the title) has separate unprocessed out. All you have to do is plug that output to your interface's inputs as you do with the processed outs.
