stuttering

[murimurimuri]

I've searched the board, but not found any concrete answer to my particular problem.

I ripped the disc (Princess Mononoke, R4) in file mode, DVD Decrypter. Then I used del_angles.exe (included with Vobblanker) to strip angle 2 from PGC 1 and PGC 2 (PGC1 = PGC 2, multiple story/angle thing). Then I processed the whole disc in Vobblanker. An warning DID pop up in Vobblanker prior to processing informing me that, due to the presence of at least one ILV cell, there may be playback issues. BUT, the Vobblanker processed vobs play perfectly in IFOedit. Upon putting it through DVD-RB (v1.09.3), however, it starts stuttering horribly (in IFOedit and my LG player). I've tried this twice from the start and the results are the same. I'm using CCE SP 2.70.2.9 trial (tried it originally with 2.67.00.27, but it was drastically oversizing), settings are more or less default (changed one or two matricies). I've tried stripping the angle in IFOedit, but I can't work out how/if you can keep the menu.

The fact that after Vobblanker processing it plays smoothly in IFOedit suggests to me that this is being caused by DVD-RB, but then I'm a bit of a 'n00b' so... suggestions?

try it without the preprocessing

only after that.. try opening it in dvd remake pro and see if there are any errors

[rahzel]

i used to my preprocessing with vobblanker, and it would playback fine on my computer and 2 of my dvd players, but 3 of my other dvd players would show stuttering.

i agree with jp, try it w/o preprocessing and see if it still stutters.

DVD-RB does not cause stuttering on non-preprocessed sources (as is evident in the thousands of successful backups)... so that would be a pretty good indicator that preprocessing might be the cause.

I'm sorry, but as I've said on numerous occasions before -- I just can't respond to trouble reports on preprocessed sources. My experience has been that the editing is almost always the source of the problem.

[murimurimuri]

Okay, I again ripped the disc in file mode with DVD Decrypter, then ran it through DVD-RB without preprocessing. It still stutters horribly in IFOedit at certain places. Not as many as before, but in one place in particular it renders the film unwatchable. I opened it in DVD remake debug, but it didn't say anything. The stuttering doesn't occur at a transition between chapters, it's in the middle of a scene. I'm not sure if DVD remake can find errors like that, I haven't used it before.

I'm using one pass VBR, but that shouldn't make a difference should it? I might try the vobblanker processed files again with 2 passes.

[jdobbs]

Have you tried it on a standalone player?

[murimurimuri]

Yes. In the standalone the unprocessed skips just as badly as the preprocessed. In fact, the skipping seems to be identical.

EDIT: 2-pass CCE skips as well... I'm going to try another Studio Ghibli disc and see if the same thing happens.

[jdobbs]

Perhaps you should post your REBUILDER.INI file. There has to be something peculiar about the disc or settings.

Sorry... I just noticed you'd already posted it.

The one very clear problem is that, as the LOG warns you, you cannot use OPV with Angles or Interleaving. That is because there are some very strict rules related to bitrate and GOP structure involved in ILVU that cannot be met with OPV.

-- WARNING: Selection of One Pass Encoding with
ANGLE/INTERLEAVING can result in incorrectly
formatted and/or out-of-specification streams.

Have you tried doing a non-preprocessed, 2 pass encode from scratch? ILVU can be very tricky and I'm afraid the preprocessing might not handle it correctly.

Just did that - couldn't test it on a standalone as it was oversized, but it skips in IFOedit exactly as every other version has. It must be either an issue with DVD-RB or DVD Decrypter. Trying Laputa.

EDIT: Watched first 15mins of Laputa (pre-processed with Vobblanker), flicked through the rest. Haven't come across any stuttering, which is strange as the disc is more or less the same as Mononoke, but I'll watch Laputa right through and make sure when I have time. Maybe it's either just Mononoke or the exact particular disc I have. I'll see if I can get ahold of another, then report back.

UPDATE:

I obtained another copy of the disc, ripped it twice with DVD Decrypter and AnyDVD, encoded in DVD-RB with 3-pass CCE on both and it still stutters in all the same places. Frankly, I'm sick to death of trying to get this particular disc to work in DVD-RB; I must have encoded it at least 8-10 times. Thanks for all the help, but I'm giving up. Perhaps I'll try it again in a few months/years with HC or a reinstalled/updated DVD-RB or CCE, but for now the time that would otherwise be wasted is going to be put to good use finishing uni work so I can watch The World Cup in peace.

@ murimurimuri

May I make a suggestion if you're up for spending just a little more time on this, have enough harddrive space and haven't already deleted your last attempt?

Try demuxing the movie with PgcDemux and then muxing the video, audio and any subs back together with MuxMan and see if you still have the same stuttering. If it's OK you can intergrate the new VOB's back into your rebuilt DVD with VobBlanker and it's Replace function. This may or may not help your situation but I think it's worth trying at least, in between World Cup matches. ;)

[murimurimuri]

When you put it so nicely, Jeffster, how could I refuse?
For one last time.. I took the rip, demuxed the first PGC of the main movie and then muxed it into VOBs, used VobBlanker's replace function and then ran it through DVD-RB as I have all the others. And it skipped in exactly the same places as the straight rip -> DVD-RB did. It's beyond me.

And my girlfriend saw this and now thinks I'm a complete geek. Ohh well...

[Jeffster]

@ murimurimuri

Umm... I might be misunderstanding your last post, but to me it reads that you re-muxed the original and then processed with DVD-RB? What I meant was to re-mux the VOB's produced from DVD-RB that have the stuttering.

Anyway it was just a suggestion, and it sounds like you might be over it by now. ;) The only reason I suggested it in the first place was it worked for me on my last backup which, coincidently or not, was also a R4 title (but it wasn't anime and the stuttering and audio drop-outs may be unrelated to yours).

[murimurimuri]

Yeah, I tried both.. because I'm masochistic. Skipped. Completely over it now.

Thank you for your help though.
