i tried to mass edit some files i burnt on dvd (Akage no Anne)
so i selected episode 1-26 on the mylist tab. choosed edit... and changed hdd to cd and storage to #051. but only the first file got changed. i tried several times
now i tried it at the known files tab with "Add to / Edit mylist" and it worked fine
The same is here with mass edit of series, only the first changes, so I think its a prob with the number of items. (iirc it had worked in earlery versions.)
