I/OMagic’s 16X DVD±RW/±R can only burn with +rw?

I have difficulty when I tried to backup some data in my PC (burn into DVD).
I tried several times to burn some data into a 8x dvd +r, but it always stopped after 2 or 3 mins after the burning process began. I have seen 2 different error messages in different times, 1) write error & 2) invalid block address. In both cases, the burning process failed.
However, I tried to burn those same projects into a 4x dvd+rw without any problem.
Why?? Is the i/o magic 16 dual format/double layer DVD±RW/±R can complete the burning process only when I use a DVD+RW???
I don’t think I can afford to use rewritable DVD everytime when I need to backup something. Anyone help?

Thanks in advance
