It worked!!! Thank you so much for your help, this is awesome.

I'm building an application that splits user-supplied videos into 
frames - what
would I look for / did you look for in ffprobe output that 
indicated this would
work? Is this likely to work for all videos with overflowed (or 
whatever) DTS/PTS or
is there some sort of logic I'd have to put in there to dispatch 
on information
about the video streams.
