dvd disc video recovery

[thom]

I made a video dvd.It played perfectly many times.as it was loaded in drive E,but not being played,the power was interrupted,now the disc won't play,and when I eject,and reinsert the disc,a window pops up and shows the disc as a blank.I tried a different dvd player,and a different computer,but all that is displayed is a blank disc.how do i fix this problem?
I would love to be able to play this disc again.
