COP Status 0x21

[Andrew Williams]

<insert favorite curses here>

  Spend 6 hours searching, draft an email to the list, and solve 
problem 20 minutes later. Compared my BDI to a co-workers and 
and discovered that although we had the same firmware, we didn't have 
the same "Logic" version in the device. Reflashed and I can 
now read the PVR correctly.

  Sorry to waste everyone's time on this.
