Comment (by sceedy):

 The code is based on information from DVDinfo which has moved to web
 address http://dvd.sourceforge.net/dvdinfo/ifo.html since I wrote the

 I am indeed donating the code into the public domain.

 I acknowledge that my code does not have a proverbial “snowball’s chance
 in hell” of meeting your coding standards. I am retired. When my employer
 upgraded from windows xp several software vendors were charging the same
 for an upgrade licence from xp as a new licence. This resulted in the
 donation of xp licences to several employees designated as “key engineers”
 for use at home for personal reasons as well as business reasons. I
 therefore have access to software that would cost me approximately £30K to
 replace, all covered by NDAs. My coding standards allow me to take
 advantage of these tools, but, they are fundamentally incompatible with

 I have had use of the ffmpeg libraries to produce program(s) for my PVR’s
 user group, which take almost all of my spare time. However I wish to give
 back “in kind”, hence donation in the form of proof of concept code. I am
 human so can make mistakes. However I hope this code will always be
 debugged, protected against errors and pass a set of automated tests.
 Unfortunately these tests can not be published because of NDAs.

 Is the above explicit enough?
