Narrative:

Upon taxiing to runway 20R; instructions were to taxi to runway 20R; hold short of runway 15. I read back hold short of runway 15. Upon reaching runway 15/33 from the east. The owner of aircraft was distracting me as I approached hold short lines; I looked left and saw it was clear. I looked right and saw a single engine aircraft at the approach end of runway. I realized I had gone past hold short lines and continued across runway. At that time; I saw aircraft start his takeoff roll. ATC questioned my actions about crossing runway and she said she will review tapes to see if I incorrectly heard her instructions to hold short of runway. Her response was to call tower later to give them information on my violation. After that flight; I informed owner of aircraft of problem that I had; and that in the future we cannot talk in cockpit if we are taxiing aircraft unless it is related to airport or other aircraft.
