That Live in Rio is available in Mexico for about 4 US dllr, lol
All the other dvd's are easily available for less than 7 US dllr each, do not waste your money on them, they must be the mexican editions, which may be a hit or miss, depending on the materials used: You may have an amazing product, better than the ones made in the USA... Or you may end having a very cheap disc, low quality in the package etc...
The first one is the same cut as the VHS version, it's actually taken from the SAME master as the VHS release.
The second link is a bootleg or more precisely a pirate DVD, and again it's the same cut, probably a direct VHS transfer.
