Recovering disk errors?

I have a phillips DRDR890 which I purchased nearly 2 years ago.

I have had it repaired in the past because of disk reading/recording errors. Unfortunately the problem has returned and I am going to bin it and buy a new one (maybe with built in hard disk).

The problem is that I have some disks that had video on them but the burning error that occured when I tried to add to the disk means that I cannot now view the origional material.

Is there any way of correcting the problem?
