Vobu Length Error

enter a title. You can not post a blank message. Please type your message and try again. This discussion is locked David Olsen3 Level 1 (15 points) Q: VOBU Length Error In Replication!? My DVD-R is being rejected by the replicator for this specific error:The calculated length of the VOBU and the length specified in the DSI field disagree.The length of the VOBU is calculated using the address of the Navigational Pack and the length as specified in the DSI field (NV_PCK + VOBU_EA = LENGTH). During the analysis, the EclipseSuite tools read from the beginning of the VOBU until they reach the next NV_PCK, which indicates the end of the current VOBU and the beginning of the next. The EclipseSuite tools keep count of the number of sectors that make up the VOBU. If the number of sectors does not equal to the length specified in the VOBU_EA field then this error occurs.In most cases, this problem has caused playability problems. It is for this reason that it is considered an error.This problem is caused during the authoring process and cannot be corrected in the pre-mastering or mastering. The image must be re-authored properly. Contact the authoring system manufacturer for more information.Anyone know what causes this problem? I've tried re-authoring the disc from scratch, re-encoding some of the assets, changing scripts, deleting the PAR files, burning the project as an image --- this problem persists. The project plays fine on all 3 DVD players we've tested it on... but supposedly this problem could mean player incompatibility issues... the Eclipse Suite marks it as a FAIL flag.

The initial tests by the duplication facility were fine. It played without problems in their gear, but when sent to the replicator the following error message was sent back http://forums.support.roxio.com/topic/26860-replicator-error-message/ to us. what does it mean, and how do I fix it.DESCRIPTION OF PROBLEMS DETECTED ON OUR ECLIPSE SYSTEM:VOBU LENGTH&NUMBER OF SECTORS DISAGREE.The length of the VOBU is calculated using the address of the Navigational Pack and the length as specified in DSI field (NV-PCK+VOBU_EA=Length).The eclipse tools keep count of the number of sectors that make up the VOBU.

Regardless of whether it contains video, the minimum http://www.gossamer-threads.com/lists/mythtv/dev/312889 playback time is .4 seconds, while the longest is 1 second.

Jan29,2008,5:23PM Post #1 of 9 (3937 views) Permalink DVD playback - average length of a VOBU? (related to ticket #4492) A few weeks ago I submitted an enhancement: Ticket #4492 - Configurable fast forward / rewind / slowmo speeds + variable reposition amount In the process, I've uncovered a bug thats been in myth for a while, but was probably never exposed because there was no gui option to change the settings. If you have ffw/rew configured to a speed other than one of the defaults (3x, 5x, 10x, etc), lets say 4x for example, then you run into a problem when playing back DVDs with the internal player. Instead of seeking at 4x, the DVD player will seek at some insanely fast speed. I've found the cause. In DVDRingBuffer.cpp, there is a variable called seekSpeedMap that is used to calculate how many VOBU's to jump at a time based on the current seek speed. All I need to do is come up with the proper mapping from seek speed to VOBUs. The code in libmythdvdnav/searching.c seems to imply that a VOBU is 1/2 a second. I tried using that, but when I tested the seek rates weren't accurate. From my research it seems a VOBU can vary in length from between 0.4 seconds to 1 second. I haven't found any useful statistics on an average VOBU length. My understanding is that there isn't any...it will vary from movie to movie, and may even vary significantly from place to place within a movie. If this is the case, then I guess you just have to make a best guess, right?. Does anyone know how the current seekSpeedMap rates were arrived at? Did someone just come up with the best compromise through trial and error? I suppose another option would be to iteratively refine the amount each time it seeks, but I'm not sure w
