Collision Errors

This happens when the video/audio channel buffers in the MPEG decoder collide 
(read and write pointer collision). This can happen when there is an error in the 
stream or on a mid-stream start.

RECOVERED ERROR, RECOVERED DATA WITH ERROR CORRECTION 
APPLIED

The Additional Sense Bytes (bytes 18 & 19) will be set to:
