What I'm ticked off about is that they're on one disc (is this verified?). This could be a minor inconvenience. However, this is unlikely, as I'm the only one in my family that even watches LBT-anything, so the likely-hood that I wanted to watch LBT X or XI and someone else wanted to watch the other at the same time is extremely unlikely.
Perhaps the biggest thing that's boiling me is that Wal-Mart had each one individually for $7.50. A good deal, but when I decided I needed them, the section that had them got assimilated by Simpsons junk, which has thrown me into this undesirable situation in the first place.
