Just recorded 4 movies on my Liteon 5005 and it stopped/failed/went Black during the finalization process. Had to unplug unit to reboot. Material could not be seen and could not finish finalization. Disk shown as invalid or "no disk"==ie a coaster by all accounts.

Put the disc in my Liteon 5045 and it showed bad disk and invalid disk errors, would not play, froze, and had to be unplugged.

On power up, I went to DVD and pressed finalize thinking it would do nothing or freeze. Instead, the 5045 (the one with a hard drive) finalized the disc and it is all there playing on both machines.

Now I have to root thru all those other failed discs.

Might also try finalizing on the computer but don't think it knows how.

Good Hunting. bobbo.
