What is the DVD Mode

DVD doesn't know all the different modes as there are in the CD world.  There's only one mode with no real name so let's call it DVD mode.

Write applications mostly refer to this mode as Mode 1 but that is not entirely correct.  The block size is 2048 bytes per block (similar to CD).
There is NO way to extract Raw data !

The DVD standard actually uses ECC blocks which contain 32 KB bytes and are 16 times larger than the CD blocks.  The error correction is superior to CD and covers ECC blocks at a time, so over 32 KB instead of 2 KB.  However, for addressing purposes, every ECC block contains 16 addressable blocks of 2048 bytes.
