Narrative:

On short final lax tower told us to turn off onto taxiway P after landing on runway 25L. As we were rolling out, they changed the turnoff taxiway to taxiway north -- 1 taxiway prior. The first officer was flying the aircraft and I took control as we turned off onto taxiway north. I acknowledged the turnoff from tower but did not hear tower telling us to hold short of runway 25R. I continued across runway 25R onto the taxiway and tower had to cancel takeoff clearance to an aircraft on runway 25R. As we crossed runway 25R tower called and said he told us to hold short of runway 25R. I did not hear clearance and therefore did not acknowledged it. We continued to the gate as per ground controller instruction. Supplemental information from acn 421955: landing behind company with similar call sign. On rollout, tower made a transmission that sounded like it was for us but used the other company's call sign. They acknowledged. We cleared runway and were instructed to hold short of runway 25R. Aircraft's nose was past hold short line when we stopped. Confusion on radio and my failure to realize how close runway 25L&right were -- only 1 hold short line between runways. Called tower. They said no problem.
