I had previously copied all Stargate SG-1 discs to folder. This gives me a folder for each disc containing the actual files of the dvd (vobs and such). Today I began ripping the episodes to mkv files which went fine for the first season (5 different discs/folders). Season 2 and 3, likely more, are giving me trouble with every disc. It can load the files, preview the video, prepare to rip, but then counts down and down on fps and up and up on the time without ever creating a file. I let it sit for some time and it did not give an error. I tried updating my nvidia drivers, restarting pc, dvdfab is already updated, moving the location of the processed file, and even tried software instead of cuda. I jumped all the way ahead to season 10 and that seems to be working fine. I could understand if one disc copy was bad but all 10 disc folders for s2 and 3? What is going on?
