ERROR: No valid vob/cell id set to be extracted! R1 DBox, Volume 5, Disc 1

[Zhonecage]

Hello, I hope this is still maintained. I'm trying to include audio and subtitles from the R1 DBox to the R2 video. So far everything worked except since episode 169, which is the start of Volume 5, Disc 1 of the american R1 Dbox. Every episode in that Disc produces the error

ERROR: No valid vob/cell id set to be extracted!

I own the original DVD and ripped it clean with DVDfab multiple times. The error won't go away. I thought DVDfab is at fault here, so I tried a clean rip with AnyDVD, but that produced the same result. The Disc I have is brand new and runs flawlessly in my DVD player and VLC. What might be the cause here? Any help is greatly appreciated.

EDIT: I don't know how many attempts I did but after the Xth attempt the error finally vanished and episode 169+ created successfully. I have not re-ripped the disc since the last failed attempt. Not sure if this is related but I started from episode 175 (the last episode in that Disc) and finished with episode 169. When I started it with 175, I saw a line that I haven't seen before and that did only appear for episode 175 of that Disc:

Auto-detecting demux information for R1 DBox episode 175...

So it could be that somehow Dragon Radar skipped using its auto-detect function for the other episodes in that particular Disc and that's why the process failed. This is just a guess as I have no clue what I'm talking about. Anyways, hope that is somewhat helpful.

Which version are you using? In the latest version I tweaked the autodetect feature a bit. Also, if you have any pertinent logs, that would help as well. Thanks

I was using the latest version 1.1.1 "Gogeta". I checked the logs, they start with episode 210 and end with episode 291, so it seems everything before that is pruned from the log file. I didn't have any issues with episodes 210 to 291.
