Sadly, I have to report that the defects in the filesets posted for both the Rainbow Munich 1977 DVD and the Rebirth Complete Shows are defects that exist on the bootlegs themselves (at least the instances of these two bootlegs that I own).
This does happen sometimes, even on major labels such as EVSD — I have seen reports of at least two instances where EVSD issued replacement CDs due to defects in their initial pressings of bootlegs.
The bottom line: I have deleted both of the affected bootlegs from this site.
I have to say, that I have been very fortunate: I have posted approximately 700 bootlegs that I personally own at Purple Hippies, ZOSO.me, and Spinster Bootlegs. I consider myself lucky that only two bootlegs have been defective.
