Sorry for asking such a naive question but here goes:

I have had some 8mm video transfered to multiple DVD+R's. I was wanting to add some menus and do some editing within the DVD+R disks. The files on the disk are organized in this manner:
Directory -> VIDEO_TS
Subdirectory -> VIDEO_TS, VIDEO_TS.BUP, VIDEO_TS.VOB, VTS_01_0, VTS_01_0.BUP, VTS_01_1.VOB, VTS_01_2.VOB, VTS_01_3.VOB, and VTS_01_4.VOB.

So here are the questions. Firstly, I have a Sony DRU DVD recorder, Is it possible to re-author the DVD's using software and re-burn them? Can anyone recommend a wat to do it and a software to do it with? I will only need to add menu's like "1956 County Fair" or things like that. Potentially add some names in the video for people in our family. Any help would be greatly appreciated. Thanks in advance I really enjoy this forum.
