Possible bug: seek bar / navigation bar does not function after backup

[orbsplateau]

After the rebuild phase, I usually create an ISO, mount it using Daemon Tools, and test the movie (using mplayer rev611) before writing the final DVD.

I use the seek bar (aka Slider, Navigation Bar, Scroll Bar, etc.) to skim through the movie and play different parts of it.

With the last 2 DVDs however, using the seek bar’s caused the DVD player to crash. The seek bar was NOT disabled in the original film (as it is in some titles) and it worked fine.

When I try to use the seek bar after the rebuild phase, the audio jumps to where it should, but the video just freezes. I’ve tried waiting 30-45seconds, but nothing changes. The audio keeps playing, but the video is frozen and the application stops responding completely.

Before I backed up the 2 last DVDs I formatted my main drive and reinstalled Windows2000SP4. I also installed CCE SP 2.70 trial, Avi Synth 2.57 and DvdRebuilder Pro 1.10.7 (in that order).

Currently using:
Dvd Decryptor
DvdRemake Pro 3.4.1 Retail (to remove certain segments & buttons in root menu)
AviSynth 2.57
DvdRebuilder Pro 1.10.7
CCE SP 2.70.02.00 Trial and CCE SP 2.70.02.10 Trial (same result with both versions)
Daemon Tools
UltraISO

mplayerc rev611 to play DVD (TY8x) / ISO file (same result in both cases)

Before re-format:
AviSynth 2.55
DvdRebuilder Pro 1.10.6
CCE SP 2.67 Retail

system configuration:
Win2000SP4
PIII 733Mhz CPU
512MB Ram
2 x 160GB WD HDs


I’ve tested the source files right before running Rebuilder and the seek bar worked fine. I’ve backed up one of my old DVDs and again, the same thing happened. I’d backed up this DVD about 2 months ago without any problems.


All the CCE settings are exactly the same as they were before... the only difference I noticed is that in the in Rebuilder’s general SETUP screen “Remove Audio DTS” is checked, but I have removed that setting and I’m running another test now.

Before I uninstall everything and go back to using CCE 2.67 and the older version of AviSynth, I just wanted to know if anyone has encountered this problem. Could it be the “Remove Audio DTS” setting?

Just as a note, the first DVD was encoded using CCE SP 2.70.02.01 and the second one using version 2.70.02.10. The test DVD was also encoded with 2.70.02.10.

Any help or suggestions would be very much appreciated. I’m really stomped. I’ve backed up ~ 75 titles so far without ever encountering this issue.

If it helps, I've attached a ZIP file containing the Rebuilder log/inf/ini files.

I could be wrong but I though DVD Rebuilder (http://dvd-rb.dvd2go.org/) was using avisynth 2.56?

Also, titles that are not one-sequential will not be able to seek. Ensure your title is one-sequential (though if the source files worked OK, this is not your problem). Do you get the same behaviour in a standalone player?

If there is no avisynth installed, DVDRB install v.2.56, but if you already have installed it, doesn't.

Maybe I'm missing something -- but if mplayer crashes... doesn't it seem more likely to a bug in mplayer? Even if there were something wrong with the ISO, the player shouldn't "crash".

I would suggest you burn the ISO to a disc and test it in a standalone player. That's a better test, as it takes other software out of the equation. If you still run into issues, we can look at it closer.

The problem is that standalone players don't have seek bars. They have navigation buttons like PREV and NEXT, and these buttons work fine... even in mplayer. The movie plays fine and everythings seems OK, it's just that the seek bar is no longer functional in the titles (even though it was fine before running Rebuilder).

burning the ISO's on DVDs (TY+R 8x) had no effect, using the seekbar caused the player to crash.

I ran a small test, where i put a 2GIG title through Rebuilder (it went through the Prepare & Rebuild but no re-encoding was necessary), and the seek bar feature was still functional after the rebuild... so whatever the problem is, it occurs during the encoding process.

This problem has never occured in any of the titles encoded with CCE 2.67 / AviSynth 2.55, this is why I don't believe it's mplayer... but I'll try an alternate DVD player software to see if the problem occurs.

I guess 'll have to restore the original programs and re-encode these titles to make sure that it's not something else... and then upgrade each component separately to see what's causing the problem..

But most (if not all) standalone players have a way to key in a time and go there.

Those routines haven't changed in many versions... but I'll check just to be sure. I wouldn't think that the ENCODE would affect it at all (as long as it is legitimate MPEG-2), but stranger things have happened, I guess.

I did several tests (just to be sure) using the slider in PowerDVD on some recently done ISOs (mounted with Daemon Tools) -- and it works perfectly. My guess is still that the problem is in mplayer.

I went back to avisynth255 & CCE267, and everything went fine. I was able to re-encode boths DVDs and the seek bar works.

then I re-installed all the latest versions of each software, one by one, and ran the same test (but this time I made sure "remove all audio DTS" was not checked), and everything went fine as well (i.e. seek bar's functional).

I'll run another test over the weekend with the "remove all audio DTS" option checked to see if I can reproduce the problem.

Weird. But strange things just happen sometimes, I guess.
