for starters, only use Nero Burning ROM and select the proper disc-type for what yer tryin to do [you can find Burning ROM in the Nero folder in yer programs list]...the rest of Nero's interfaces [smartstart, xpress, etc] will only screw stuff up...and yes, you need ALL the files in the Video_TS folder [.ifo, .bup, & .vob files]

to burn a "watchable" copy [i.e. on yer home DVD player]:
--Open Nero Burning ROM
--Select "DVD" and then "DVD-Video"
--Drag *all* the files from the show's Video_TS folder to the Video_TS folder in the project's window
--burn away

also, some home DVD players will only play DVD-R discs, some DVD+R, some both...also, some can play DVD-RAM discs and others can't...you'll have to look up yer particular model to find out
