When I convert my TV show database from xmm7 I get a list of episodes, rather than a list of the TV shows. i.e. each episode has its own database entry, rather than just the show. So, for example the series "24" has 193 database entries, rather than just one entry with the 193 episodes inside it.
It also loses the catalog numbers in the original database. What am I doing wrong?
Only thing you're doing wrong is using XMM8 TV Shows and episodes a handled a little bit different from XMM7. At the moment I don't know if these entries are doubled but I think that there is only a link to these episodes in the movie table. An extra table for episodes I think doesn't exist anymore. Your problem with the catalog numbers seem to be a bug in XMM8.
