In my opinion a CRC is enough because the need is to catch a corruption 
and not to authenticate, and 1/1^32 per slice (Matroska has also CRC but 
only per slice) seems a good balance to me (overhead vs usefulness)

I personally have a a PoC for error correction code at the container 
level (Matroska). I think that it is a better place for ECC because the 
whole content, including the container, would have to be repaired.
