Well, i tried but it only plays the first map and when it comes to the second, it glitches out, is there any way i can like cut it down so it would be just the second map, which is the part i need?

/record demoname - and when the map ends /stoprecord - then when you have the second map you just do another /record demoname, /stoprecord. You can't record both maps unless you stop your first demo.
