DVR keeps failing to record


I have a Wharfedale DVDR24HD.

For the last few mounths it's been playing up. I'll be recording something and everything is fine untill it gets to the point of ending the recording and it will say 'failed to stop recording' and won't of recorded it. Which is so annoying!

Not only that but the disk won't record again afterwards. (Even more annoying!) Sometimes it won't let me erase the disks either. It works erasing them on my laptop but I don't really wont to risk using the disk again if the DVR seems to find it faulty.

It's started happening a lot more often over the last few weeks and it's at the point where it's just not reliable anymore. Is there a way to fix this? Is it just that mine must have broke? Is it worth getting a new one or would I be better off getting a different DVR? If so, any ideas? What's good atm?



Thank you for your help! (That is if you do, of course.)
P.S. It is the DVR that is faulty, not the disks isn't it. I really doubt it is the disks though, I've used quite alot of them and they used to work fine.
