In case anyone else comes across this, I can confirm that 00544.mpls is the correct playlist for the retail version of the disc. My disc did not have 00920.mpls, but it did have 00544.mpls and 00058.mpls. I watched the segments and compared them against the DVD to verify that 00544.mpls was the correct one.
