I have some PAL home videos that are interlaced and I would want to make an NTSC DVD+R as well as a PAL DVD+R from it. What I need to know is if I should keep the entire project in interlace mode or should I de-interlace before mastering to DVD?

Also will Ulead Media Studio Pro do a decent job of converting my interlaced PAL video to interlaced NTSC?
