[PATCH v2 0/5] MR7466: mf: Fix some issues with seeking.

[Conor McCarthy (＠cmccarthy)]

This fixes failure to play the prologue video in Planet of the Apes: Last Frontier, which unpauses by calling Start() with a location. The exact state leading to this issue does not occur in the Start() tests, and it's not clear how to reproduce it reliably.
