UDF DVD Disc Format For ALL DVD Players
Create ISO file to ensure Video Playback

We recommend you create a .iso image file from your mastered DVD files. This way you know for sure we copy your files exactly using all the file system formats you may have embedded in your mastering process. If you do give us a zip file containing your DVD files, we WILL burn them in the most compatible way. This means your DVD will have the UDF 1.02 file system format as well as the ISO 9660, JOLIET, IFO (DVD-video) format.
