Thanks, Dan. I finally got it working and the solution is very 
instructive (and worrying).

This:
C:\CMD & tiny apps\ffmpeg >ffprobe -f lavfi 
amovie=G:\VIDEO_TS\VTS_01_1.VOB,ashowinfo
--note current working directory--
fails; "Error initializing filter 'movie' with args 
'G:VIDEO_TSVTS_01_1.VOB'"
--note missing '\'s in path to 'VTS_01_1.VOB'--

And this:
C:\CMD & tiny apps\ffmpeg >ffprobe -f lavfi 
amovie=G:\\VIDEO_TS\\VTS_01_1.VOB,ashowinfo
--note escaped '\'s in path to 'VTS_01_1.VOB'--
fails; "movie=G:\\VIDEO_TS\\VTS_01_1.VOB,showinfo: No such file or 
directory".

But this:
G:\VIDEO_TS >"C:\CMD & tiny apps\ffmpeg\ffprobe" -f lavfi 
movie=VTS_01_1.VOB,showinfo
--note change of current working directory--
succeeds.

Quick! Hand me the bug killer!
