Understand Nero corrects ifo/bup files which have incorrect information on files allocation structure on a DVD disc or/and file size - to fully comply with DVD standard.

The error is caused by a cheap/crap authoring software and some standalone recorders.

In such case people should not worry that MD5 won't match as *.VOB files stay untouched and they are the most important as they contain video and audio stream.

Please note that some players (i.e. Sony) won't recognise a DVD video disc burnt in UDF mode.
