Vobblanker problem

Vobblanker seems to change frames and playback time in any PGCs after processing: ORIGINAL: PGC_1 (program chain): [Title(TTN): 1] [00:00:02.10 / 25 fps] (Programs: 6) (Cells: 6) (uses VOB-IDs: 1,2,3,4,5,6) [Ch 01] [Pg 01] [Cell 01] [V/C Id: 1/ 1] : time: 00:00:00.10 / 25 fps [Frames: 10] [Ch 02] [Pg 02] [Cell 02] [V/C Id: 2/ 1] Layer Br.: time: 00:00:00.10 / 25 fps [Frames: 20] [Ch 03] [Pg 03] [Cell 03] [V/C Id: 3/ 1] Layer Br.: time: 00:00:00.10 / 25 fps [Frames: 30] [Ch 04] [Pg 04] [Cell 04] [V/C Id: 4/ 1] Layer Br.: time: 00:00:00.10 / 25 fps [Frames: 40] [Ch 05] [Pg 05] [Cell 05] [V/C Id: 5/ 1] Layer Br.: time: 00:00:00.10 / 25 fps [Frames: 50] [Ch 06] [Pg 06] [Cell 06] [V/C Id: 6/ 1] Layer Br.: time: 00:00:00.10 / 25 fps [Frames: 60] VOBBLANKER: PGC_1 (program chain): [Title(TTN): 1] [00:00:02.04 / 25 fps] (Programs: 6) (Cells: 6) (uses VOB-IDs: 1,2,3,4,5,6) [Ch 01] [Pg 01] [Cell 01] [V/C Id: 1/ 1] : time: 00:00:00.09 / 25 fps [Frames: 9] [Ch 02] [Pg 02] [Cell 02] [V/C Id: 2/ 1] Layer Br.: time: 00:00:00.09 / 25 fps [Frames: 18] [Ch 03] [Pg 03] [Cell 03] [V/C Id: 3/ 1] Layer Br.: time: 00:00:00.09 / 25 fps [Frames: 27] [Ch 04] [Pg 04] [Cell 04] [V/C Id: 4/ 1] Layer Br.: time: 00:00:00.09 / 25 fps [Frames: 36] [Ch 05] [Pg 05] [Cell 05] [V/C Id: 5/ 1] Layer Br.: time: 00:00:00.09 / 25 fps [Frames: 45] [Ch 06] [Pg 06] [Cell 06] [V/C Id: 6/ 1] Layer Br.: time: 00:00:00.09 / 25 fps [Frames: 54] Also type flags changed: the sequence 3/9/11 (in PGCEdit) became 2/8/10. I use version 2.0.0.2, any suggestions? Sorry for my english and thank you for replies.

That does not look right - it's obviously an ARccOS disk but the minimum frames, AFAIK, is 0.4 seconds (10 frames in PAL). The flags are because VobBlanker can not process angles. What has happened is that the angle flag has been stripped. I also have a problem with VobBlanker and cell flags. In any event, I would use a pre command (instead of break) to skip over this rubbish and get to the correct start of the movie (which will be somewhere past chapter 6). Regards

On many DVDs, I have seen the Seamless Angle flag set on all cells without reason. In these cases, it is harmless to remove them.

Hi all, Sorry, but I'm not familiar with pull-down... This is how I re-calculate the duration of each VOBU. I'm not decoding the MPEG video, just trusting the PTS values located in the Nav. Cell duration is calculated adding all VOBU's duration. Code:

Sorry, The things I thought(1.pull-down, 2.the number of GOP in last VOBU) are probably no reference with the change of playback time in IFO. I examined other 3 examples, and one of these is same as above example(pull-down, 2 GOP in last VOBU), but it's playback time didn't change by processing.
