Sony Dvcam DSR-250 Hard Drive Camcorder

I use this camera at work. I just took it out on a shoot and I get back. When I go to look at my footage, it's all bad except for a few minutes. Everything else is choppy and half of it only has audio and a few cut ins.
in my mind a good camera should always record properly.
The camera is only 3 months old and has gone in for repairs twice!
I am not happy with this camera!
