Hi, Joe  -- thank you for reporting this awful crash.  We want to solve this, but I can not create a crash with any of my small, ( Itried about 5),  {input}.dv files so I downloaded a sample "pond.dv" file (105MB)
    
https://sourceforge.net/projects/libdv/files/examples/examples/pond.dv
  /download?use_mirror=pilotfiber&download=

and that does not crash either and I started with an empty $HOME/.bcast5 file and Fedora O/S.
Could you email me the small test file you use?  If we can create the failure, we can fix it and you can avoid having to pre-process your files in ffmpeg first.  You can email the file if small directly to me phylsmith2017@gmail.com or upload it somewhere and let me know.  This will help !!

1. Start Cinelerra GG official build on the Oct 31, 2018 10:50:41, OS: Suse 15.0
2. Menu: Settings/Format: choose preset PAL 576I - DV(D)
3. Menu: File/Load files (create new resources only) - choose an arbitrary DV file (eg. one with length of ~5 secs, 20MByte), click on OK

then immediate crash. If I start cinelerra from a console, I see following messages:
...
*** buffer overflow detected ***: cin terminated
Aborted (core dumped)
