I burn with Nero (works with 6 and 7 as far as I know). I simply create a new DVD-ROM disc, create the VIDEO_TS and AUDIO_TS directories on the disc, then drag all the content (VOB files and whatnot) to the VIDEO_TS folder. I've also used strictly verbatim media in the past, though that's mostly because it was the cheapest good media I could find. I don't know if that makes any difference or not.
