1. Is it generally suggested to burn ISO files instead of raw files (vob files, etc)? I burned a dvd today using raw files and it played on computer but not on dvd players (PS4 and Xbox 360). Burning program was imgburn. When I burned with ISO file it worked correctly on dvd players. I used Verbatim DVD-R media. 2. Assuming one is using a modern dvd player like the PS4 and reliable dvd-r media, why do some burned dvd's play on computer and not on a dvd player? Does it have to do with computers having more codecs vs dvd players? 3. Whenever I burn dvd's I always test them on a dvd player, not on a computer, for reliability. Is this a good practice, or should I test burned dvd's on both devices? 4. I gave someone a dvd recently and she could not play it on her iMac laptop. The laptop was purchased in the past year, but I don't know the exact model. She went to Applecare for support and they suggested burning the dvd in mp4 format. I am pretty sure that would not work on dvd players, however. I am ready to advise her to simply install vlc media player on the laptop to play this dvd. Is this a smart idea? Appreciate the advice.
Never noted any difference in playback between burning an iso image or the VIDEO_TS folder structure. The only (dubious) advantage that I see is that you can mount an iso as a virtual disk. I have seen disks that play OK on the PC that burned them and fail miserably on a standalone player - it always came down to disk quality - the codec point isn't relevant iansmuch as both PC or standalone player has to be able to handle mpeg2 video and the standalone player, built by the thousands, is the final judge. There are Verbatim disks that use the AZO dye and then there are 'Life Series' Verbatim disks that are fit only for the landfill. I don't know of any standalone DVD player that can handle mp4 video (burning a 'DVD' in 'MP4' format is a contradiction; a DVD disk comprises VOB, IFO, BUP files in a VIDEO_TS folder, while an mp4 file is simply burned to CD or DVD as data).
