I'd ask each of my trading pals for their preference - to send the raw Data Files (the VIDEO_TS files) as a Data-DVD, or if they want it burned as a Video-DVD.
Several DVD Burning Packages will see "VIDEO_TS" and its contents and automatically suggest these are buned as Video-DVDs. It may take me some 'confirmation' nags to insist, "Yes, I know these are normally video-files, but I want them burned onto a plain Data-DVD format, not as a Video-DVD."
But I'd ask the trading partners. If they didn't have a preference, then I'd ask what they wanted to use these files for - to plug my disk into their DVD player and watch immediately, or do they want to save the files onto their computer's hard-disk and watch from there.
