I'm sure they only reprocessed these two cards to the new format
167 Jana H - California Suit
321 Carmen Gemini - Majestic View
Why these 2 i think it's because both were/are in the Welcome Pack every user gets first when he installs the software.
Since it is noticeable in the shows files size i'm sure that's all as i checked the filesize of all shows when i found Jana H (and found Carmens show in the process)
But also 2 other shows have been completely redone
567 - Morgane - Love Cruise
583 - Melisa - Hot Waitress
They already were in the new format so i don't know what was changed.
But when i had all cards redownloaded these 2 redownloaded all clips while most others weren't downloaded at all or only some clips i deleted or renamed which means that every clip changed in some way.
I reported these findings here:
