I have the same issue with PowerDVD 15 Ultra fresh installed on my new laptop.
PowerDVD Ultra 15.0.4630.62, Windows 10 x64 1809, CPU i7-8750H, GPU GTX1070 8GB, 32GB RAM 2666MHz.
Multimedia catalog > Film/TV spins forever looking for connection... and in the end reports: "PowerDVD cannot connect to the movie information service...".
Internet connection is perfectly working, I don't have blocking firewalls and AVs, the program can successfully check online version and updates, and I can access to
Video online > YouTube for example...
Tried also to delete %LOCALAPPDATA%\CyberLink\PowerDVD15 but didn't solve the issue. One entire week has passed and still the same error. Tried also changing DNS with free ones like Comodo DNS, Watch DNS, Norton DNS but nothing changed.
