A few users report this, but I can find no answer in the forums... Description of the problem : Backing-up a DVD9 to DVD5 using DVD Rebuilder 0.89 with installer and CCE SP v2.50, default settings. Some DVD backups are successful, while some come out too small (eg 2.7 GB instead of 4.3GB) with poor quality and a warning upon rebuilding: - Rebuilding segment 23 VOBID: 1 CELLID: 24 - Possible dropped frame(s) noted in this segment, continuing... Anyone knows where this error stems from? Random hardware error, wrong DVD structure, inappropriate set-up, known bug? Thx in advance!

did you recently update CCE? i had exact same problem on 3 movies in a row,, i reinstalled the previous version of CCE and everything was fine from then on (i have basic) so maybe this doesnt help
No, I haven't reinstalled CCE... It just worked fine with previous DVD's until I had this problem with my latest DVD. I'll keep you posted if it occurs with another DVD. As a result, I think it might be a problem with the source DVD, however I don't see anything wrong with it. Afterall I shrunk it with DVDShrink 3.1 and the result is flawless.
Are you using one of the 2.70.x versions of CCE? This seems to be where people are having problems, and it depends on the exact bitrates required so it won't happen on every disc. I believe the most recent version has a fix for this problem (don't know if it's completely fixed or not since I still need to d/l it myself).
No, I'm using version CCE SP 2.50. However I had previously tried CCE SP v2.70, then uninstalled, and then installed CCE SP v2.50. Do you think some files could have remained from my previous install?
I suppose I could have just read the thread title to answer that. Don't mind me I'm just the village idiot around here But no, as long as you have DVD-RB's setup pointing to the correct exe file there shouldn't be any reason you need to worry about a different version.
I tried again to back-up another DVD and it worked perfectly. Moreover, on my DVD that failed to back-up, I tried twice and I got the error "Possible dropped frame(s) noted in this segment" both times, resulting in a 2.7GB large back-up. So indeed this error occurs systematically with some DVDs, whereas it does not occur with other DVDs. Also, maybe this error occurs when compressing at a given bit rate...
1) Why noone has ansvered the question? I have absolutely the same problem. I am glad someone has already described the problem so well. I can add that dvd becomes 2.7 because Rebuilder wrongly calculates bitrates. I discovered it before rebuilding and set ~2300 to 2800 kbits in all 31 cells except last (32) with titles. 2) I thought the problem was because I modified avs scripts. Rebuilder constantly makes outdated d2v files so I make them with DGIndex each time after Prepare phase. Besides dgindex makes in case of Solomon wrong reverse pulldown. It combines wrong frames and leaves interlanced those ment to be combined. I can see it in VirtualDubMod. Rebuilder writes then in the 32 avs files the video is interlanced. I indexed main vts vobs with None field operation and wrote a word macro to add the line: Telecide(Order=1,Guide=1).Decimate(5) to each file and remove interlanced from convert to yuv command. 3) I do not understand why Rebuilder does not allow to set indexing options (like which dll is used to create d2v - I have set 100 times in options different libraries, copied them to rebuilder directory - no use - I still get message - outdated d2v file) and complete control of whats written in avs. 4) After all I need only to rebuild the dvd. Why I cann't take the original dvd folder, take m2v file and remux it with both language and subtitle files. Remuxing in ifoedit makes unplayable video. Maybe there is the same problem with IfoEdit which Rebuilder has?.. I tryed also to author new dvd in ifoedit and raplace vobs in old compilation from new, then get vts sectors and strip vob id, but it does not remove the information that vobs were 7 and now they are 5!
Probably because they haven't had the problem. I've never seen it myself. DVD-RB doesn't do any IVTC so you should expect strange behavior if you force it in an AVS file. DVD-RB just looks at the original MPEG flags to see if the video is interlaced. If it's encoded with a hard telecine (which is the only time IVTC is necessary) the original and the backup will both be interlaced. If you force IVTC in AviSynth DVD-RB won't get the correct number of frames to rebuild. If you have a PAL DVD that's actually progressive but is flagged interlaced (and even though I'm in NTSC country I can verify that these exist) you should select the Disable "Interlaced" in the Advanced (Expert) Options sub-menu of the AVS Options menu. The way you're doing it you'll end up with the wrong number of frames and no pulldown will be applied unless you do it yourself. Because DVD-RB creates the D2V file itself to make sure things are done in a way that they can be rebuilt exactly like the original. I can't answer all of this, but in general you won't necessarily be able to use the M2V files from a DVD-RB project with any other program. Some of the MPEG flags aren't actually set until the rebuild phase, particularly for pulldown and framerate. Basically, you don't have all the MPEG information until rebuilding is done.
1) If I add pulldown to all files will they be rebuilded properly? 2) Here is hader from rebuilder d2v file: Stream_Type=1 iDCT_Algorithm=2 YUVRGB_Scale=1 (0:TVScale 1CScale) Luminance_Filter=0,0 (Gamma, Offset) Clipping=0,0,0,0 (ClipLeft, ClipRight, ClipTop, ClipBottom) Aspect_Ratio=4:3 Picture_Size=720x480 Field_Operation=0 (0:None 1:ForcedFILM 2:RawFrames) Frame_Rate=23976 Location=0,0,6,6B900 Why Field Operation is None, but Frame Rate is Forced Film. Probably thats why it makes dvd 2.7 instead of 4 GB!
Nope. All video is going to be encoded at 23.976fps and then changed to the appropriate framerate during rebuild. That allows hybrid sources to be encoded without changing the framerate of either the film or video portions. Otherwise either film sections would have to be changed to 29.97fps (ie hard telecine) or video sections would be telecined (losing fields and making it jerky as a result).
Video is already encoded at 23.976. Can it be rebuilded? What is Pulldown=0 setting in REBUILDER.INF file in working directory?
Okay, let's backup and go over exactly what the possibilities are with film based material and DVD-RB. For the purposes of this explanation we'll assume a segment made from 1000 film frames. 1) The original DVD was encoded correctly as progressive frames and pulldown flags are present. The actual video stream has 1000 frames, but when played back it has 1,250 frames. The D2V file will reference the original 1000 frames, which will be encoded at 23.976fps. 2) The original DVD was encoded incorrectly with a hard telecine. Instead of having 1000 frames that are read as 1,250 frames there are actually 1,250 frames. The D2V file will reference the original 1,250 frames, which will be encoded at 23.976fps. In either case, during the rebuild stage the framerate will be changed to 29.97fps wherever the original has that framerate and pulldown flags will be added where they appear in the original. You may be able to alter that behavior by changing settings in the INF file, but it wouldn't be as simple as changing the pulldown flag. You'd also have to change the ECL files to match the number of frames and frame type. Even with all that I suspect there would be other problems that couldn't be solved without altering the actual code used to rebuild.
1) Changing settings in rebuilder.inf file does not work. The rebuilded video runs at 1/5 faster then audio. The video has 1000 frames which become 1250 through 2/3 telecine. I do not care whether it was hard or not. Now I have cristal clear, smooth 23.976 video which I want a pulldown to be applyed during rebuild. Is it too much to ask? 2) Rebuilder certainly miscalculates something. It can be seen clearly because it sets ~2300 bitrate for 173 min. video when there should be 2800 kbits (all other material except 10Mb menu is blanked). The miscalculation proportion is 23.976/29.7 or 2300/2800. Check the bitrate calculator http://www.videohelp.com/calc.htm. Video has 224 kbit english and 384 kbit russian 6ch audio. And 2 subtitle streams.
Since that's not what DVD-RB was designed to do yes it is. If that's your goal you chose the wrong program. DVD-RB doesn't miscalculate. It's been used by at least tens of thousands of people on millions of backups and if it was calculating things wrong it would have been reported and fixed by now. Since you clearly know more than jdobbs about this you should write your own program. As long as you know everything there's no point in trying to explain anything to you.
I finally set the correct paths to correct dll's and rebuilded dvd complately with Rebuilder and this turned out to be true. But why? Why is this? Video comes at reduced quality and with visible compression artifacts unlike when I use inverse telecine which produced me perfect video? Why such essential settings are not left open for editing. Who is the author protecting his software from? I will have to strip the DVD off the menus and reauthor it myself because of this simple elimination. :-(
