NEW to DVD Burning. DVD-RW Erasing

[donscomp]

Very new to this. Was wondering. If you erase a DVD -RW will you still see the previous burn in the disk itself? I did a test and it wouldnt play on our DVD player. But I read that a lot of Players will not read the -RW's.
It plays on the Burner itself. So I earased it and I still see the burn from the disk. Is this Normal?

Thanks all.

As far as I know, that should be normal (if you are referring to the back side of the disc, the part that "changes" when it is burned...)
