Bug found in DVD Decrypter ???

[kLOsk]

Thus I have the following problem. I encode repeatedly with the Big Three and have already much experience with errors in Scenarist etc. however that me really ever did not happen. The SOURCE is a DVD9 with 8 gb. I has like always an image provided around it then with daemon tools too mounten.. goes also everything without problems. Dvd of decrypter attitudes are all puos remove and logical-prove also the protective mechanisms if I the image mounte are everything correct. Film runs up to ends through and everything is ok. if I now DO it nearly 4 u start and the image clean-load receipt I the completely normal messages the film have keinne double Vob ids or something similar eifnach 7 gigabyte main film and the remainder a few extras. thus leave I more dvddecrypter the film ribs (after pgc is believes I the standard) runs now also everything without problems, up to the main film like said the main film is 7 gigabyte, but dvd more decrypter hears simply on after 3,6 gig further ribs. the READ speed goes suddenly highly on 20 or 30x and more dvddecrypter runs einfahc through up to and 100 % the filesize remains equivalent with 3,6 gb. wenns finished is have I stop the directory and is 3.6 gb m2v a file in it and stop 7 did not point there to be should I have the image shcon twice again geripped the same then have I always tries more dvddecrypter not over DO it nearly 4 u now too start separate everything by hand, but comes exactly the same error raus. I have also tried directly from dvd the drive assembly to ribs without an image to provide. however the error is still the same. I use the newest dvd more deccrypter verison 3.5.1.0 white no more which I otherwise still try out could. possibly another older version however naja... if someone white which be could would be I gratefully for nen advice in in such a way the READ mode is everything well however then in the file mode gibts proboelem: - /

so this text got translated by babbelfish.. i hope you understand it.. if not i have to translate by hand :(

Main problem i have is.. when i rip by pgc in dvddecrypter it simply doesnt rip the whole 7 gig vob. it stops at 3,5 gig and then runs further till 100 % and got no errors or soemthing.. but its just only the half movie ripped...

Hi
try du make an image with Alcohol, mount it and then try dvddecrypter.

[kLOsk]

i already did an image using dvd decrypter.. this works without problems... i can play it. its macrovision and puos free. i just have the problem when i want to rip it then in ifo mode....

[jel]

... babbelfish creates some interesting translations ... you may want to edit 'DO it nearly 4 u' to correctly read 'DoItFast4U' :sly:

anyways, if i understand you correctly you are having trouble ripping your movie in .ifo mode from a mounted .iso image? and that this behaviour is the same whether using DVD Decrypter manually or via DoItFast4U?

is this correct?

if so does DIF4U give you any error messages? could you please post your log file.

cheers

[kLOsk]

no it doesnt gives any error messages... dvd decrypter also doesnt handle as if it founds an error.

its starts ripping in ifo mode and after ~ 55% ripping speed gets up to 20x and it runs till 100% but the file size doesnt change.. it stays at 3,9 gig for the file... after that dvddecrypter closes and dvd2avi starts... so. i also tried a old dvddecrypter but the same shit happens... meanwhile i also did anothzer dvd and it worked the normal way.. so there must be a problem with this dvd.. is there any opportunity to use smartripper or soemthing like this for the file i need ???

[Trahald]

you can sorta use smart ripper. you would have to rip in its ifo mode.. then rename the files to match what dif4u names the dvddecrypter files.. also take the delay out of the audio and rerip the subs with vsrip/vsconv to srt. basically you have to do everythign dif4u does.. then use reauthorist to calculate the correct bitrate. read: not easy

you can also try to mount the image with alcohol or nero and see if dvddec has an easier time with that. there may be a problem with the image for some reason

If I remember correctly D3s7 had a similar problem with a menu, and it was resolved by forcing the 'File system to parse' under General settings to ISO9660 instead of Auto. Worth a try i reckon.

[kLOsk]

i now did use smartripper .. and hey it did work.. was manual shit but its good now :/

[D3s7]

if your .vob is > then 1024MB, you need to tell DVDDecrypter to switch to ISO9660 mode (it's a setting in there)..

if larger then 1024, in theory the file descripter in UDF mode should use 2 index bits... however many don't.. they use one (if I remember correctly what causes the error)

DVDDecrypter "assumes" a smaller file size and only demuxes part of your asset based off that...

[Eyes`Only]

DoItNearly4U! Hahaha.

/me is contemplating a name change...

[kLOsk]

it wasnt bigger than 1024 mb... :)

[LIGHTNING UK!]

I'm guessing it was caused by mismatching vob / cell ids between the IFO and VOB files - leading to certain ones being skipped.

[influenza]

DoItNearly4U! Hahaha.

LOL

[kLOsk]

but if it would be a failure in ifo it would just run to 100% percent. but the problem i got is that it speed up to reading speed of 20-30x and runs through to 100 % without changing the file size.... also. why was smartripper able to do it correctly then ??

Reading via deamon tools, it's quite likely that you'll see those speeds - if not faster.

Maybe you dont normally because you're reading / writing to the same physical drive? As the program isnt processing those certain bits of data, it's not writing anything.

Smartripper probably uses a different method for IFO parsing. I check what I'm ripping matches the IFO file. Maybe it doesnt.

[kLOsk]

no. i always read using daemon tools and i have speeds ~ 10 x but like i said it just happens always at the same part of ripping process. it starts to get faster.. if there wanst be the 100% reached it would fasten up to 1000x. so it doesnt read... so i dont know what it is..
:)

[D3s7]

I believe what he's saying is that when a problem is encountered daemon tools may not report the accurate speed.... so while it's saying it's speeding up, it may not be.

Either way, sounds like there might have been some problems with the ifo reprint incorrect sectors which caused DVDDecrypter to hicup....

SmartRipper might process the IFO differently

you could try as a test ripping in file mode by vobid and see if it still has an issue (just as a test)

[LIGHTNING UK!]

What I meant by the whole DAEMON Tools speed thing is that clearly reading via the virtual drive, you're actually reading data off your hdd.

If at the same time you're decrypting to the drive, you've got loads of random read/write operations going on at the same time.

That's why you only get 10x.

I would expect lots more than that when reading from a hdd. More in the region of 20 - 30x.

Because IFO mode is skipping data in the VOB stream (due to mismatched vob/cell IDs), nothing it being written to the hdd. Therefore the hdd is JUST being read from (by DAEMON Tools) and so you're seeing these faster read rates.

Hopefully it's clearer to you now what I meant :)

[kLOsk]

yes it is :) ok then... but hmm shouldnt you think about a mode where this failure doesnt happen... ?? at least i got this dvd ripped with smartripper and encoded as i always did.. with dvddecrypter this wouldnt be possible. so maybe you should think about an option like skip errors in ifo file or something.. because the dvd runs without problems even though there are failure in the ifo :/

[LIGHTNING UK!]

I would, but as you're the only person who's ever mentioned this problem to me, it's not worth it. Not only that, you could have still used File mode to decrypt the data so it's not like you REALLY couldn't use DVD Decrypter to backup the disc. You might just have to use other tools/methods.
