When this problem has happened to me it was because of a bad rip. When BD-RB rebuilt the files the video encoder couldn't get past the glitch in the incoming data, so it lost its reference to the next frame data, and the video file became blank, or stuck, after the glitch while the audio continued.
So take a look at your new back-up disc and take note of the exact time where the video freezes. You'll want to explore this spot on both your original rip and your BD-RB rebuild files.
Play your original rip file and move to that spot in the film. Watch very closely to see if there is any hiccup in the playback at that spot. It could be a brief scrabbling of pixels, or a shudder in the motion, or something like that. If you detect any non-smoothness in the playback then a bad rip is almost certainly the culprit.
If you didn't detect a bad rip then repeat the process by inspecting the BD-RB rebuild file. If you detect a problem in this file, but not in the original rip, then it could be something has interfered with the rebuild process. This would be quite unusual, but possible nevertheless. Could be a power surge, hint of upcoming HDD failure, etc. If you don't detect a glitch in the rebuild file then your problem is most likely a bad burn.
So:
1. If there is a glitch in the rip then -> re-rip.
2. If there is a glitch in the rebuild then -> run BD-RB again.
3. If there is no glitch in the rebuild then -> burn another disc.
To check for this type of problem I now simply play back the rebuild files on my computer to make sure that there is video and in-synch audio at 3 positions in the stream; at the start, middle and end. If the video and audio are OK at all 3 positions in the rebuild then I will burn the disc.
