Yes it can be done!!
Here is the deal. I recorded a 55-minute concert broadcast in XP-PCM mode on my Sony RDR-HX780. I prepped the program cutting out unwanted stuff, titled the disc and chaptered the songs. I purposely did not finalize the disc just to see if I can finalize it in my PC.
Here are the steps I took.
1) Popped the disc in PC. PC did not recognize the disc in the DVD drive.
2) I started Nero Recode and pointed to the disc drive and Nero immediately recognized the un-finalized disc in the drive.
3) Nero would copy the disc and ask me to insert a new disc and Nero would burn and finalize the program on the new disc.
4) Nero did not “recode” the MPEG-2 files and in fact kept the chapter marks intact. Of course there was no menu, as I didn’t create a menu using my RDR-HX780. Now that the disc is finalized as DVD-Video - any PC program including Nero can create a menu.
So if anyone has a broken Pioneer or Sony with the Pio/Sony operating system and you have unfinalized discs – you can finalize them without recoding using Nero.
I wonder if Nero will work with unfinalized discs from a Panasonic or other recorders?
