Occasionally CD-R and CD-RW discs written by a CD-R/RW drive cannot be read by other CD drives. These unreadable discs may need to be read using the CD-R/RW drive they were created with. The disc written using the CD-R/RW drive might not be readable by CD-ROMs other than Multi-read compatible (UDF compatible) CD-ROMs.

Multiread compatible (UDF compatible) CD-ROMs are CD-ROMs that can read low reflectance and support Packet Write.

Please note: Certain software (i.e. particularly those including Video playback) may require a considerably increased specification PC to give acceptable results. While this Blu-ray Disc & HD DVD-ROM Drive can read DVD-video or BD-MV(BD-ROM) discs, decoding them to display on your pc’s monitor requires separate MPEG, H.264 or VC-1 decoding that is done by separate hardware (either an MPEG, H.264 or VC-1 decoder card or MPEG, H.264 or VC-1 decoding done by your video card), or separate software that you install to do MPEG, H.264 or VC-1 decoding. For further details, refer to the documentation that comes with MPEG, H.264 or VC-1 software.
