Just another DVD problem

I created DVDs using NERO in the following way:
I started a DVD Data project and dragged and dropped the VIDEO_TS and AUDIO_TS folders from my hard disk. I burnt the compilation without finalizing it (in case I need to modify it). But when I played it on my DVD player, they malfunctioned (the menus didn’t work or wrong mapping of video items or not playing itself). The DVDs work if I do it by the DVD-VIDEO project option.

Is there any way that I can make this DVD play in my player or any way to convert this Data project into Video project (since I’ve not finalized)?
Or do I have to throw there discs away and do them again by the DVD-Video option?

Finalize the disk, may work.
