thanks again for new!

Some audio CDs are encoded with HDCD. On a normal CD player they play just like a normal CD in 16 bit. However, there are CD players which can detect and make use of the HDCD coding. Which results in the audio tracks being enhanced to something more than 16 bit (something between 16 bit and 20 bit). This technology is usually only used for audio CDs and not for movies. Now eac3to can detect HDCD tracks and decode them which basically means increasing the bitdepth from 16 bit to something a little bit higher than 16 bit. If you have hardware which supports HDCD you will not want eac3to to decode HDCD, but let the hardware decode it instead (that saves space). But if your hardware can't do HDCD and you do have some HDCD audio tracks, eac3to can now decode them to full bitdepth.
