You obviously not knowing the AVI specs doesn't make this claim any 
more valid. A 'valid file' is a file that meets the specs. There would 
even be valid OGM files if anyone had properly written down OGM specs.

The AVI header has a flag (AVIF_MUSTUSEINDEX) of which, as the name 
says already, the purpose is to indicate that the index is necessary, 
and the OpenDML index points to the beginning of the data, not to a 
chunk header, and the specs do not mention that there would have to be 
a chunk header preceding the point an index entry points to.

Those files are valid AVI files, you can turn it around as much as you 
want.
