Comment:

 (In [15319]) Fixes #4420. The actual segfault reported in the ticket no
 longer exists in svn trunk, but this changeset makes sure we always check
 for a null ringbuffer shortly before checking the InDVDMenuOrStillFrame
 state.

 PS The backtrace was only partial and matched neither svn trunk nor
 0.20-fixes so I couldn't trace down where exactly the null pointer was
 used in tv_play, but the partial stacktrace did tell me the functions
 involved and this fixes all the InDVDMenuOrStill() calls in the TV
 class...
