I cannot find log files for DVDFab9 on my Win7 Pro installation at this time. All that I have are DVDfab 8 logs Please direct me as appropriate so that I can attach them to this thread. Per your faq:
C:\Users\User Name\My Documents\DVDFab\Log
At first I thought that this problem was merely an aberration however I am able to duplicate this behavior.
1) Insert the Blu-ray "The Blues Brothers" into your Blu-ray player.
2) Open up DVDfab9 and select the extended version.
3) Use M2TS Passthrough.Default
4) Output your file.
5) Play the M2TS file. I use Media Player Classic Home Cinema. The file will play fine.
6) Perform the above procedure with DVDfab8. You will be able to play that M2TS file just fine as well.

The times for the three videos are reported by Windows Explorer as 02:27:37, 02:27:46, and 02:27:45 respectively. I am unsure why there is a file size difference between the DVDfab8 and DVDfab9 files. The settings appear to be identical. MediaInfo confirms it.
My workflow in this instance is to import the M2TS video into Sony Vegas however it hates that format. I use FFmpeg to create a lossless (pass through from source, actually) output of the video and convert the audio to stereo AAC audio. From there I will perform my editing as appropriate.
The command line is included however only the bottom of the output is shown for brevity.

Please note that the messages above are "normal", albeit annoying, in that many people run into this when remuxing content. This does not affect the playback of the video. The example above ran to completion and provides the length of the output video after the remux/reencode of the source file. No frames were duplicated or dropped.
Below is the same output as above. I did not complete the conversion because the "Non-monotonous DTS in output stream" warning stopped both the first time I did this and the second time I did this.

When I perform an encode against the DVDFab9 created file multiple problems happen. Please note the duration of the input file is 02:27:45.93. The original output file, which has since been deleted, was just over three hours long due to the high number of frames duplicated. The results were aborted during the second encode for replication purposes.
My script performs a check for the input frame rate using MediaInfo CLI so that I can calculate the right bit per pixel density and two pass encoding for bitrate accuracy (H.264 runs just under the specified bitrate in it's first pass, single pass, and for live content). Frames will be duplicated or deleted to maintain proper cadence (See also Scott Pilgrim vs The World or "Moon" for cruddy examples of frame rates changing from once scene to another in the same MPEG-PS VOB file).
The output line from my encode shows "dup=51252 drop=3061" This is not the case when I use the M2TS file from DVDfab8.
There is a time correlation between when FFmpeg performs it's demux of the DVDfab9 content in that:
1) DVDfab9 content ceases to report the "Non-monotonous DTS in output stream" when it is converting to MP4. DVDfab8 content continues on with that message until the video is finished.
2) DVDfab9 content needs to have frames duplicated and dropped "dup=51252 drop=3061". DVDfab8 content neither duplicates nor drops frames.
When I play back the DVDfab9 content that was converted to MP4 by FFmpeg it has horrific stuttering. DVDfab8 content does not.
I believe, however I cannot verify, that I have used DVDfab9 previously (2011-08-21) on this same source content without issue. In my reproduction I did not remove the Blu-ray from the drive. In my initial encode I did.
This is the only piece of content that I have had an issue with when using DVDfab 9.
Again, please direct as appropriate so that I can attach the DVDfab 9 log files to this thread, but to the best of my knowledge DVDfab 9 is not creating them.

When I perform an encode against the DVDFab9 created file multiple problems happen. Please note the duration of the input file is 02:27:45.93. The original output file, which has since been deleted, was just over three hours long due to the high number of frames duplicated. The results were aborted during the second encode for replication purposes.
My script performs a check for the input frame rate using MediaInfo CLI so that I can calculate the right bit per pixel density and two pass encoding for bitrate accuracy (H.264 runs just under the specified bitrate in it's first pass, single pass, and for live content). Frames will be duplicated or deleted to maintain proper cadence (See also Scott Pilgrim vs The World or "Moon" for cruddy examples of frame rates changing from once scene to another in the same MPEG-PS VOB file).
The output line from my encode shows "dup=51252 drop=3061" This is not the case when I use the M2TS file from DVDfab8.
There is a time correlation between when FFmpeg performs it's demux of the DVDfab9 content in that:
1) DVDfab9 content ceases to report the "Non-monotonous DTS in output stream" when it is converting to MP4. DVDfab8 content continues on with that message until the video is finished.
2) DVDfab9 content needs to have frames duplicated and dropped "dup=51252 drop=3061". DVDfab8 content neither duplicates nor drops frames.
When I play back the DVDfab9 content that was converted to MP4 by FFmpeg it has horrific stuttering. DVDfab8 content does not.
I believe, however I cannot verify, that I have used DVDfab9 previously (2011-08-21) on this same source content without issue. In my reproduction I did not remove the Blu-ray from the drive. In my initial encode I did.
This is the only piece of content that I have had an issue with when using DVDfab 9.
Again, please direct as appropriate so that I can attach the DVDfab 9 log files to this thread, but to the best of my knowledge DVDfab 9 is not creating them.
