Intervideo dvd music copy issue

#1

When copying dvd music files from various artists dvds - to one dvd - using interv3 I find that the dvd when played back freezes at what appears to be a title of the next artists movie/song recorded.
They show up on initial insertion into DVD player as seperate titles.
It would be great if these copied titles played continually to be able to create party mixes.
Is this a problem with the Intervideo software or am I missing something.
