Finalizing dubbed DVDs

I dubbed a TV program stored on my DMR-E85H but didn’finalize it. As I would like to play this DVD on other DVD players I realize that I haveto finalize it before I can do this. I can’t figure out how to finalize this DVD so that other friends canb watch it. I know that I should be able to do it via my DVD recorder because I have produced and finalized several other DVDs in the past, However, I have not finalized an existing pre-dubbed DVD before and all my efforts have been unsucessful so far. Can anyone help me out?

I finally figured it out. I found out that I could finalize my dubbed discs by switching the operation from HDD to DVR and selecting Disc Setup from the DEMR-E85H menu. Although I had done it before, I had just forgotten how to do it. So no problem = all is fine.
