(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...

but when i was going to submit that last night the site stoped loading
