Yes, but you have to set a retry timer. I set mine for like 45 mins and it just keeps retrying until the timer is up. FreeRapid definitely doesn’t bypass the delays.
Anyway, the BD50 files are the main films. The Bonus Features discs are BD25 save for the ROTJ/Trilogy one which is also BD50. So altogether there are 6 discs. 4 are BD50 and 2 are BD25. The actual films in BD25 are not available anymore. Just BD50.
