Nero Recode 2 features Nero Digital, the world’s fastest MPEG-4 encoder, and enables a user to recode non-copy protected movies (DVD-9 - DVD-5) to any CDR/RW, DVD+/-R or a single DVD+R DL disc in DVD-Video format (DVD-9 to DVD-9). If the source DVD is larger than 4,7 GB, Nero Recode 2 can compress the contents so that they fit onto an empty DVD disc without any noticeable loss in quality. Also, you can convert DVD-Video titles that are not copy-protected to the Nero Digital™ format (MPEG-4) and then burn them onto discs. Nero Recode can compile DVD-Video titles (not copy-protected only) onto other media (CD and DVD).
If you have DVD-Video titles on separate DVDs and would like to compile your favorite titles onto one DVD, you can use Nero Recode 2 and burn the desired DVD-Video titles onto a single disc. You can burn the compilation onto DVD or CD. Finally, you can convert from 5.1 Dolby Digital Surround into space-saving Nero Digital™ audio format and remove unwanted audio tracks, subtitles or bonus material to gain more space.
Note: I know it's an old version...but I think it's more reliable than newer ones...
