DVD's are not encoded like Data Disc's at all!
I'm not sure if it's the file order (like VCD) or some kind of disc-format difference, but that sort of burning just won't work.
The good news is that there are a myriad of reliable progs (many are free and come with no hitches) for just this sort of situation.
http://www.videohelp.com is where I usually go for these kind of tools. If you already have Nero (or for that matter any DVD burning software), just look around in the menus for a mode that says something like "Burn Image" or "Burn DVD Files"--yes, it is that simple. Unlike CDs where you have to use "Music" discs for Audio CDs, DVDs are all the same physically apart from the dye chemistry.
Speaking of dye chemistry... I recommend burning to DVD-R (dash) rather than a DVD+R (plus) for wider compatibility. Most DVD players today can play anything (-R, +R, -RW, +RW, and sometimes one or both DL types) but older units are more iffy. If that's the case, I recommend "+RW" for test-burning (to make sure it works right when played) and "-R" for the final product. Also,
http://www.nomorecoasters.com has a nice index of disc quality by brand and manufacture. Sony and Verbatim and the best for "-R" discs, and you can get them off-the-shelf in nearly any store. DON'T USE STORE-BRAND DISCS!! TDK used to make excellent quality disc, but they started outsourcing about a year ago to CMagnetics--"cmags" are okay for "+R", but there "-R" disc are ready for the landfills.
Have fun!
