You Can"t................................. Nero is Not a DVD Authoring program it is Just a Burning program that Makes really Crapy Quality VCD"s and SVCD"s...what you need is A DVD authoring Program and you need Mpeg2 files that are DVD Compliant,...One DVD authoring Program that is super easy to use is "Tmpgenc DVD Author" it would be a Good Place to start but if you Mpeg files aren"t DVD compliant you will also need an Mpeg encoder.....
1. "Nero" is just a line of products that start with the word "Nero" 2. A specific program called "Nero Vision Express" can do the encoding you need although it is really crappy, untstable and unreliable so I wouldnt reccommend it 3. When you have encoded the movies to VOB/IFO format you can burn them using Nero.
Like I said you need a DVD authoring Program, It will take your Mpeg2 files and The Menu"s and Chapters and format them into Vob files inside a Video_TS Folder that ten gets Burned to a DVD-R...You can Use "nero Vision express" for this But if your Mpeg2 files are DVD compliant it will Allways re-encode the Files which Greatly reduces the Quality that is why you should use a Real DVD authoring Program like the one I mentioned in my Fors reply...Cheers
What i do now is use DVD Shrink 3.0 which converts all the files off the dvd to the appropriate files you need, then use nero 6 to put them onto a dvd.
Tmpgenc DVD Author is Probably the easiest DVD authoring Program out there But it doesn"t make very Snazzy Looking DVD"S..I like to use DVD-Lab because it has a Lot more Features and you can really customize your DVD to make it Look the way you want, you can download a 30 day demo of it at : http://www.mediachance.com/dvdlab/" ....Cheers
