Cannot get seek bar to work on .vob file, Please post

[matt163201]

I have a Laser Disc RIP that was converted to DVD of the ORIGINAL Star Wars Epsisode 6, the only problem with it is that I CANNOT use the seek navigation bar on my media player. I have tried MPC, VLC, Power DVD6, WinDVD 5&6, and still no go. I think it has something to do with the .ifo file. But I am not sure as I am new to DVD stuff, I was able to add a .vob file to play on the movie before the movie almost as a intro, and no the seek bar didnt work before I added the file. If I play the .vob files separatly, it will let me seek, but if I play it like a stand alone player would (video_ts.ifo) it will play fine, be able to skip chapters and fastforward and rewind but no seek. I have the other two (episode 4 & 5) and the both seek and do everything else. if need be I can upload the .ifo file from Episode 6 and the one from 5 or 4 for reference. Any help wpould be appreciated. Have also tried ifoedit and pgcedit and both have seemed unsucessful,but maybe youll have better luck then me.

Please Post

Probably your TMAPTI table is empty.
If there is room to put the indexes inside, VobBlanker will remake it. Just open the DVD in VobBlanker and process as it is.
If there is no room, try to make it with IFOedit. (although you can experience some crashes, so save a copy of your IFOs).

I have posted the .ifo files in a zip file for people to look at to see what is wrong, dont worry its just two ifo files, one wthat works with the seek (episode 5) and the one that doesnt (episode 6) nothing else is in it. NO VIRSUES OR SPYWARE OR ANY GAYNESS. open before extracting to see if you dont believe, I just want to get this thing fixed. SOMEONE PLEASE HELP, I hope this helps so you know what to look for.
Thank you guys for your responses, Matt163201

The files you zipped up were not the correct ones to identify any problem with time seek. VIDEO_TS.IFO does not contain information related to playback of titles, that information is contained in VTS_xx_1.IFO - xx being the number of the titleset that the title is in.
btw, I can look at the files, but according to the rules, I can not approve them for public access.

[matt163201]

So should I post the files that you need or because of rules should I not? Should I maybe email anyone who wants to take a look at the files, maybe you? Just tell me which files you need and I will send, obviously not the .vob files, too big.
Thanks for responses.

If you post them I and any other mod can see them, but not the general public. I can look at them to see if the table is there, but so can you. Use IfoEdit, open the VTS_xx_1.IFO file that corresponds to the movie, and click on VTS_TMAPTI - this is the time map required to seek by time.

[matt163201]

here is all of my .ifo files from the episode 6(not working) and here are all the ifo files from episode 5 (working). Hope you guys can help me out. Thanks

As jsoto figured, there is no time map. Take his advice on how to fix it, and spend a little time with IfoEdit so you can see for yourself what is missing. Look at all the PGCs (click on VTS_PGCITI to expand the tree), the one with the longest run time is usually the main movie. In this cas it is PGC 1 of VTS_01. Now open the time maps (VTS_TMAPTI) and look at the map for the first PGC (the first map) - it is empty. Without a time map time seeks cannot be performed.

[matt163201]

My internet just got back up after a storm last night (cable), and I see the advice and I checked the timestamp folders of the two and see the difference. I cannot do anything right now because I have a summer class that starts in like 30 mins, damn college, but I will defintly give it a shot a little later and I will tell you guys whats up. BTW since your a moderator maybe this has some importance to you, DVDecryptor is no more, they shut down the project.

Thanks again for all your help!

update: i used VOBlanker with settings untouched and now i can seek, BUT the seek bar doesnt move but it will go to the spot that I point to :angry: man I didnt know this crap could be so difficult, to make it worse there are NO GUIDES online for VOBlanker that talks about seek options only cut and paste and audio kinds of stuff, jsoto if your still looking please post

[jsoto]

VobBlanker does not create space in TMAPTI to put the required indexes in. It only fills the available (if any) space with right pointers.

So you have to create the required space in the IFO with IFOEdit.

[matt163201]

how do i do that, could you please guide me a little, how much work is that gonna be you think and does this matter for a stand alone player. BTW I this is a Laser Disc converted to a DVD, the other two episode 4 & 5 were also too. I dont know if this has any merit on anything.

Interesting... I've also encountered matt163201's non-work slider symptom when reauthored DVD. I get the non-working slider symptom, after blanking out chapters 1-12 of 25 in PGC 1 with either VobBlanker or another tool, and then adding a cell command to cell 1 to jump to cell 13 with another tool. I've discovered I can get the slider working by loading the files into VobBlanker, and then blanking chapters 1-12 again. (A simple load and save as you suggested doesn't seem to work. Perhaps in my case the TMAPTI is no empty, but needs to be updated.)

[mpucoder]

It is less likely that the time map disappeared and was recreated than something simpler happening. Seeking by time can be inhibited 4 different ways (3 PUOp masks and the "non one-sequential" flag).
Adding a cell command, if this is the first jump/link/call type cell command, requires changing the title type (TT_TY in VMG_TT_SRPT) to show that jump/link/call command(s) exist as cell commands. In that same byte is another bit that denotes "non one-sequential", and also 2 uop bits. Either bit 6 (non one-sequential) or bit 0 (prohibit time play or search) set will stop time searching.
You can check this byte using IfoEdit, but be aware that the table is misnamed VMG_PTT_SRPT, and the byte is called "Title playback type". It is also not interpretted properly. What you are looking for is an odd value or a value greater than or equal to 0x40 (64 decimal)

[blutach]

The easy way to do this is in PgcEdit. Go to utilities - title play map table and if any titles have PPUOps sets just click clear PUOs. OK and save.

jsoto

how can i create the required space with ifoedit?

[Dimad]

You can also try importing the disk into DvdReMake and then exporting it. DRM recreates most of the tables from scratch anyway so it may fix your search issues.

Probably there is more than one PGC in a VTS Title.
Multi PGC titles and parental block titles have no time map.
One_sequential_PGC titles are the only kind that have time maps.

Just adding a technical, bit by bit, reference to mpucoder's explanation.
