BleepingComputer.com: Connect a PVR HDD to a PC

I need some advice. I have an old analogue Samsung HDD TV Recorder (PVR). Its functions have gradualy been going wrong lately and it is due for replacemet with digital model. It does still have several programme recordings that i am reluctant to lose. The machine has a DVD-R drive which no longer works and I have been using a Video grabber device to copy programmes to my PC to burn on DVD. This has proved time consuming and unsatisfactory.

I read somewhere that you could take out the HDD unit from a PVR and connect it directly to a PC but i do know know what other hardware or software i might need or even if it is possible. Can anyone help me here? I dont have the hardware specs to hand at the moment, but i will look it up and post them if this helps.

Thanks
