Query: Buyer Beware

The 4 disc version that Amazon offers is a DVD-R set, and it comes in one case. For those not familiar, DVD-R's are the recordable DVD's that are sold in stores, with odd colors on the bottom side. Though it is guaranteed to play, realize that this also effects the potential resale value. Other major website retailers do not deal with this version, and second hand stores may not take it on trade. The 3 DVD set that comes in a 3-case box is the official version that one would expect, and is commonly sold throughout the market.
