[mythtv-users] errors compiling NuppelVideoPlayer.cpp

[toad six]

Hello all,

I'm trying to upgrade to .17, and I'm getting compile errors in
NuppelVideoPlayer.cpp:

NuppelVideoPlayer.cpp: In member function `void
NuppelVideoPlayer::StartPlaying()':
NuppelVideoPlayer.cpp:1868: error: `mutex' undeclared (first use this function)

I also get a ton of errors saying that db, lock, and unlock are
undeclared as well.  What am I missing?

Thanks in advance...
