Mostly: broken files mis-detected as DV. Could of course be avoided by
adding another check on top of the libdv check in the demuxer, but
that's extra effort...
Maybe a bit unfair, but that the last activity of any kind on libdv
seems to have been in 2006 could maybe be considered a concern.
Also the native DV demuxer is one of those places that regularly allocates > 100 kB
on the stack and disabling libdv is a quick way to disabling that
demuxer.
If libdv works with the libavformat demuxer, just ripping out the native
DV demuxer might be an option, too, though.
