Dead space 3 freezing all the time randomly

It seems that freezes happen at transistion scenes more than anywhere else. Doorways (airlocks) elevators, or right after a major battle. This is where you get an inventory or progress saving message or an incoming message from the other people. I watch the hard drive indicator light on the ps3. I find that if i do not move or touch the controller ( don't even move your player) until the game is done with whatever I have limited the number of freezes. I have saved the game at the end of each sucessful "progress saving" point. Quit the game and copied my save to a flash drive. That way , when the freeze does happen - and it usually wipes your save file to where it now says o percent complete- I can reload the save and begin again. Isn't this a sad way to have to play a game??? Takes hours and hours of wasted time to work around this stupidity. BTW i am playing this now on my third user name - second disc- and third ps3 console. I have managed to make it midway through my first new game + with only a handful of freezes but with the save file backup plan I am progressing. The other 2 playthroughs i do not have a "clean" un frozen save file. trying to restart at "last uninterupted point" will let me restart but the game will freeze at about the same point as the last time so progress is at an end for those user names unless i delete the save and start all over. But remember- it is not the games fault- it is your ps3 or xbox consoles fault. Never mind that no other games do this- its a hardware error on your end- not the game disc.
