And from the same line, some weapons can still instantly kill you. It doesn't change the fact that my character is getting wiped out or seriously injured during Cinematic Scenes. You also get them when you are not in VATS. So again, the problem is not being able to turn off the Cinematic crap.
What you are experiencing isn't usual vanilla behavior. You say you play on the PC, are you playing with mods that change gameplay? Also, I'm assuming what you are describing as "cinematic scenes" is VATS? This is different that what is going on in NV.
Also, as a side note, you absolutely can turn off the Cinematic Scenes in New Vegas. It's done, IIRC, in one of the options menus. I play on the PC. It isn't faulty. I turned it off right away because my companions kept getting kills and it put my character into the slo-mo cinematic camera and it was driving me crazy.
