The only error on this set is transfered straight from the source; the missing welding footage. The video is DAMN close to, and occassionaly arguably superior to, the "TR47" set, though it has some softer, muddier moments as well. The audio has been compressed, and looses a TINY amount of punch because of it. All in all though, a perfectly acceptable choice, I think, and the commentary helps make a strong case for getting this set.
