error in Dif4U - PGC has 3 cells but only the first was extracted

[jarthel]

investigating further by looking at the ifo (using ifoedit).

I found that PGC4 where the error occurs has 3 cells: V/C ID:14 to 16.

V/C ID 14: 4:25 minutes long
V/C ID 15: 4:15 minutes long (with Layer Br label)
V/C ID 16: .1 secs long (with Layer Br label)

I opened the .m2v created by dif4u in vdubmod and the length is only 4:25 minutes. It would a reasonable conclusion that this corresponds to V/C ID 14. I looked opened the corresponding audio file and its length is 8:40 minuts which is the correct total length for PGC4.

What happened to V/C ID 15 and 16? opening the DVD image in Dif4u and DVD decrypter verifies that this PGC should have more than 8 minutes of data.

Can someone help? Thanks

ps. my attemp at fixing this is to extract the PCG4 using dvd decrypter (muxing the stream into a separate .m2v file) and renaming the output file to correspond to the filename created by dif4u. haven't verified this. just doing it now.

update1: utter failure with my attempt. DVD decrypter extracted the first cell only. I must include that PGC3 which is similar in format to PGC4 (2nd to the last Vob ID has layer br label) was successfully extracted (meaning I got the correct length).

update2: tried smartripper this time. same story.

Is it possible that the video is shorter than the audio?

run a search on m2v length mismatch with reported times and you will find it is a common theme.
all perfectly normal and nothing to worry about.
if you load the .m2v into scenarist it will (should?!?!) report the correct time.
hope that helps

why the .m2v file? Why not the .mpv? Also I used "the big 3" guide on this. And I got this scenarist error -->> http://forum.doom9.org/showthread.php?s=&threadid=70942.

Thanks for the reply.

okay, all i was answering was why the .m2v can be reported to have an incorrect duration by some programs.
as for the error.....i dont think i can offer any other suggestions than the ones given, beyond importing that problem file manually and seeing if that solves things.

paste in here the layout of that PGC (as shown in ifoedit)

my guess is 1 of those 3 cells is a layerbreak and is dumuxed your just not seeing it properly.

also, what version of DVDDecrypter?
