Ensure the material is in the proper format and works correctly. We recommend testing the source disc on multiple devices (for CD-ROMs and DVD-ROMs), as well as on CD players (for CD-Audio) or DVD players (for DVD-Video).
For added security, we recommend sending two source discs. Mark source discs with designated markers. NEVER use a pen! Compress your files in ZIP or RAR formats.

Note: XDISC S.A. does not interfere with the content of source discs and is not responsible for inaccuracies in the provided material or errors copied onto produced discs that do not result from the pressing process. For materials longer than 78 minutes, we reserve the right to exclude complaints regarding sound quality or disc functionality.
