Run-time Error 5

[ChickenMan]

Just got my first problem with RB, Run-time Error 5. I'm running Win XP SP2 and using RB v0.67 with CCE 2.50 SP. I then tried RB .57, .50 & .37 all with identical problem.

The DVD I'm trying to backup is Farscape Season 1 Disk 2, PAL Region 2&4. Disk 1 worked fine with no problems. There are 4 VTS sets on the DVD and no subtitles. Just 2 English Audio which I unselected the 2ch AC3 and kept the 5ch one. In the Prepare stage, RB runs through VTS 1 fine (as expected) but instantly it tries VTS 2, the error window pops up. I hit the OK and RB shuts down. Checking the D2SAVS folder, the V02000000001001.AVS & V02000000001001.FLG files existed but 0kb in length. I then tried older versions of RB as I quoted above, same problem.

I then tried running the DVD through Shrink 3.2 with No Compression for the 4 episodes but set the extras and Menus to 90%. RB on this also failed with same error.

Finally I ran VTS_02 VOB's through DVD2SVCD using same CCE and let it author it with DVDAuthor. No probs there, all went well. Copied the 2 VOB files produced over the top of the 2 VOB files of VTS_02 in the original rip, used IFOEdit to GET VTS Sectors, then run it though RB. Bingo, all is now working fine with no errors and backed up successfully:)

Checking the original VTS_02_1.VOB in Bitrate Viewer, I found at the 13 sec mark one GOP with a length of 47 !!! All others were 15 or less. I assume thats what caused the problem.

A GOP with at length of 47! That's definitely way out of spec...

[ChickenMan]

When I re-encoded with CCE (via DVD2SVCD and Avisynth) it didnt flinch and re-encoded it fine. There are bound to be other DVD's like this so do you think RB would be able to handle these in the future ?

Hmmm.... I suppose so, but where do I draw the line? 47, 147, 2047? I would be willing to wager that section of the DVD never gets played -- because I think most players would choke on it.

[ChickenMan]

No problems then, sounds to complcated to include then. At least I found a way (maybe not the simplest way) to overcome the problem if it occurs again. Thanks.

During playback of both the original and the RB version, both show a slight jerk and all out of focus for about a second at that point. Its just following a scene change. Thats both on my DVD Player and on the PC with WinDVD.

Would it be possible to detect the problem and provide an appropriate error message? E.g., "GOP length of 47 detected; this is not supported."

(Then, we offer a prize for the person with the longest GOP, and that'll tell you where to draw the line. :) )

@ChickenMan.

I am very curious you know...

It would be very nice to know if passing this title through VobBlanker is of any help (No blanking anything just open the VIDEO_TS.IFO and process it...): just in case the GOP is in an unreference section, this may help to remove the problem...

[ChickenMan]

@Sir Didymus I ran the VIDEO_TS through VobBlanker leaving everything at default and all I got was a VTS_01_1.VOB at 1,028,472 length and ALL other 42 files at either 0kb or 1kb in length. Same for Disk 1 of the Farscape series as well. Tried other movie DVD's and they processed fine. Obviously VobBlanker doesnt like these DVD's either :(

Shrink 3.2 does not show up and un-referrenced content on the DVD.

I'll also increase the GOP frame buffer to some ridiculously high value. But truthfully I would expect that it will never get hit again... or do you think this was a purposeful attempt to prevent reencoding?

During playback of both the original and the RB version, both show a slight jerk and all out of focus for about a second at that point. Its just following a scene change. Thats both on my DVD Player and on the PC with WinDVD. So the GOP with 47 frames is actually part of the normal DVD playback?

[ChickenMan]

Yes, it appears to be. I have cut the problem section out of the VOB file and is too big to post here (5.4mb) so have sent you a PM with its D/L addy.

In this little clip, he goes to wack a small robot on its head, the screen goes to static for a couple of secs, then a scene change to a space ship flying forward. Checking the timings, I'm sure the GOP thats 47 long is actually the static part.

[jdobbs]

I just fixed it for version 0.68. They'll have to make a helluva big-ass GOP to get bigger than the new GOP limit.

If these Farscape discs are anything like the R1 releases I'd say it's probably to prevent re-encoding. The R1 discs seem to be designed to be difficult to do make any changes to when backing them up. They have a completely $#@&!ed up structure that's difficult to do any editing on without breaking them and the episodes tend to be around 3GB each despite being very compressable video. I've always gotten the impression that they're either authored by morons or geniuses.

Slightly related, I get a Run-time Error 5 when I first run rebuilder version 0.64a, and 0.66a. I solve this by copying a previous rebuilder.ini file to the folder, it runs.

This is on win98, and this reminds me of what happened with older versions starting after 50b and I think ending at 55b. If it's re-emerging, I don't know what version it started at.

Thanks, I'll try it out when 0.68 arrives in the mail.

[jdobbs]

I also noticed in testing that the segment that immediately after the anomaly, the video gets skewed (even on the original). Notice how the spaceship in the frame following the white noise shows extreme blockiness. This looks a lot like a read error...

[Sir Didymus]

Ahhh, read errors...
I see. If this is what happened to your rip, I start to understand how it is possible for an original title to show such absolutely uncommon GOP sizes...

[dragongodz]

i will just chip in with an experience with these dvds.

a freind bought the farscape box sets and went to back them up with instantcopy(this was months ago). he was having some troubles so he asked me to have a look. wow some weird authoring. example 1 dvd had 3 episodes as 5.1 audio but 1 (episode 3) was marked as 5.0. if played from the start(play all episodes) the 3rd episode would not start when the second finished. you could only start it by selecting that episode from the main menu. i had a lend to test it on my player. it worked but had to read several times before episode 3 would start. thats the original dvd i am talking about.
so anyway i told him to just use dvdshrink and it worked ok(picture quality was not the best possible but atleast he wouldnt wreck the originals). i should mention the backups from shrink still had the exact same problems as the originals with playback so no it wasnt any read errors or bad media etc.

so yes in my opinion farscape R4 are badly authored. whether on purpose or just done by idiots i cant say. :)

[NobbyNobbs]

Is this the Australian Farscape discs (R1 & the european R2 are just 1 or 2 dual-layer discs each season, R1 = 11 disc's in season 1, R2 = 10 disc's each season)

[dragongodz]

yes this is the Aus dvds. 6 dvds per season with 4 episodes per dvd except for the last, which has 2(of course) plus some extras etc. the first 5 dvds only contain a trivia type game thing which takes up bugger all room, besides the actual episodes that is.

[NobbyNobbs]

The new Starburst edition in R1 looks like they have just put it on double sided disc's instead of reauthoring the disc's over on dual-layer.:devil:

It should be possible to put these on 6-dual-layer disc's without messing up the authoring.:angry:

Sorry, but no way is it a read error. Yes, I noted the same blockiness in the spaceship, I originally thought this was the problem point, but checking timings, that occurs after the long GOP. In the Bitrate Viewer pic above, this part is where the Q value is plummeting down from 30.8 to eventual -0.6, I have seen this before on other original DVD's and the following scene is always blocky.

Yep guys, it sure is the Aussie R4 release. The only reason I'm backing this up is for a friend who originally used Shrink and results were shocking. RB is a "bit to complicated" for him, hence I get called in for help.

[dragongodz]

yep as i said not good. the only thing you can do to get a reason version is compress the hell out of the menus and the trivia bits(which arent big to start with of course), drop 1 of the audio tracks and use AEC on smooth. thats atleast watchable. :)

[Le_Zouave]

I just want to say that I have the same problem with the french edition of Absolutly Fabulous Season 1.
It's impossible to get a good result with a transcoder as the runing time is 198 min.
The other disc (1 disc per season) were just fine.

[jdobbs]

I should be releasing v0.68 this weekend and it has a fix for this. I've been working on ILVU compression code -- but if I can't get it done early enough I'll disable the routines and release it anyway just to get this and a couple of other small fixes out.

[ChickenMan]

Just like to add that the new version 0.68 encodes the problem disk with no errors. :) Thanks for the fix jdobbs.
