    How does a DVD player know it's a CDR disk? It's been burned as a UDF/ISO DVD disk. What is it that tells the DVD it's a CDR and not a DVD disk??

    A CD-R has different physical characteristics from a DVD. Most players that officially support the use of CD-R/RW don't even use the same laser in the drive for CDs and DVDs. The drive has to know what kind of media is loaded just to read any data from the disc.
