(fixed 2.5.4) Time mapping problem

[Chewy]

I have been been having time display playback issues with exported episodic dvds using DRM since I started using it. At random times during dvd playback, the seconds will "studder" on the display. For example, the seconds will count :06, :07, 06, :07, :08, :09, :08, etc. This happens randomly, sometimes during a small part of a cell, most of a cell, or many cells. This is not isolated to just a particular standalone or software player (It shows up in the same places on everything I have tested). This problem does not affect actual playback. The discs I have burned played back flawlessly with no video or audio studders. My main concern is that if I would switch to a different brand of dvd player than the ones I have now, it may cause problems with FF/REW, frame advance, or skipping chapters. This time display problem has been happening since I started using DRM, starting with version 1.0.1 up to the current 2.3.4 pro release. Being no one else has noticed it, I figured it had something to do on my end until now. Every episodic dvd disc I have backed up with DRM has it to some extent while any other programs I use including blanking out cells with MenuEdit and following up with IFOEdit does not exhibit this problem. I have not noticed the problem with progressive type DVDs although they may have it as well. My collections I have tried with DRM that exhibit this problem include any DVD from all the seasons of the Sopranos, Star Trek: The Next Generation, X-Files, Farscape, Andromeda, and Sliders. Thanks to an excellent piece of software, Mark's Tray DVD Player Professional, I now have a means to demonstate the problem. I started off with Sliders, Season 1&2, Disc 4, and ripped it with DVD Decrypter 3.2.3.0 onto the hard drive. Next, I played both the original dvd and the ripped versions through the Tray Player and compared the DVDAnalysis.txt files. Both matched perfectly, so the rip was ok. I then imported and exported the rip through DRM Pro 2.3.4 without using any editing functions of the program. I then played the DRM exported file through the Tray Player and compared that DVDAnalysis file to the ripped one. These are the differences I observed: First, the control panel total running time was different. The DRM export showed 2:57:41;27*, while the rip/original dvd showed 2:57:34;21 (with no asterisk. With the help of the Tray Player help file, I found the following: Whilst playing a movie, the 6th item in the Status Bar denotes the total playing time as HH:MM:SS:FF. Tray Player does not rely on the total time as reported by the PGC's header block as this has proven to be somewhat unreliable. Instead Tray Player attempts to calculate the running time by adding together all the cell times in the PGC. If, for any reason, it is unable to do this calculation, it will resort to using the PGC's header block time but will append this with an asterisk, eg: "1:32:36:00*". The last difference was in comparing the DVDAnalysis.txt files. Below, are the PGC times reported in the analysis file. Original/Ripped Times: TTN-1: PGC-1. Reported: 0:44:31:25 Actual: 0:44:31:25 in 5 cell(s) TTN-2: PGC-2. Reported: 0:44:32:10 Actual: 0:44:32:10 in 5 cell(s) TTN-3: PGC-3. Reported: 0:43:59:07 Actual: 0:43:59:07 in 5 cell(s) TTN-4: PGC-4. Reported: 0:44:33:04 Actual: 0:44:33:04 in 5 cell(s) TTN-5: PGC-5. Reported: 2:57:33:16 Actual: 2:57:33:16 in 17 cell(s) DRM Exported File: TTN-1: PGC-1. Reported: 0:44:34:06 Actual: 0:44:33:25 in 5 cell(s) TTN-2: PGC-2. Reported: 0:44:34:02 Actual: 0:44:34:10 in 5 cell(s) TTN-3: PGC-3. Reported: 0:44:01:05 Actual: 0:44:01:07 in 5 cell(s) TTN-4: PGC-4. Reported: 0:44:33:09 Actual: 0:44:35:04 in 5 cell(s) TTN-5: PGC-5. Reported: 2:57:41:27 Actual: 2:57:41:16 in 17 cell(s) As you can see, there is a difference in PGC times between the original dvd and the DRM exported one. I have also checked other problem export discs and they show similar time discrepencies. All the editing and command features I have used, and that is plenty, work great. The only problem I have had with DRM is this time mapping one. I would greatly appreciate if someone could look into this problem either by my method, or another preferred one, and verify this is indeed a bug. Thanks, Chewy

Thanks for a very detailed report. We will take a look. Is it for NTSC disks?

[Chewy]

Yes, all the discs are Region 1, NTSC. The problem really shows up when running hybrid type dvds. I will try a 100% pure interlaced dvd and a progressive movie dvd later today and report my findings. Chewy

[Chewy]

I ran the same test on a couple more DVDs using the same method that I used in the first post. The following are the results. * NTSC/R1/4:3/100% Interlaced Movie * DVD Tray Player control panel total run time: Original/ripped = 1:10:37;06 (no asterisk) DRM export = 1:10:41;06 (no asterisk) Original/ripped DVD Tray Player DVDAnalysis.txt PGC times: TTN-1: PGC-1.

I get the same problem too. I just checked a load of my old dvds I editted in DRM and most of them show the problem 04, 05, 06, 05, 06, 07, 08, 07, 08, 09 etc I will have to check if they are nstc (most are) but the last pal dvd I editted did not show the problem.

Hi and welcome to the forums hopester thanks for your feedback

[Chewy]

Thanks for replying hopester. At least I now know I am not the only one seeing this problem.

[old-hack]

I'm just tagging along with this particular issue. Noticed it for the first time yesterday. Now I know you can go backwards in time.

[hopester]

Still has the bug in 2.4.0

[Chewy]

I still see it too. No mention of a fix in the version history so I wasn't really expecting one. Oh well, back to menuedit.

[DimadSoft]

Could you please check if 2.5.3 fixes the problem. Thanks.

[Chewy]

I sure will and thanks for looking into the problem. Chewy

[Chewy]

Problem is still there using Mark's Tray DVD Player Pro 1.9.9A and my standalones consisting of a Pioneer DV-45A, Pioneer DV-434, and Apex 500. For the test I used Sliders - Seasons 1 & 2 - Disc 1, NTSC R1, and ripped it with DVD Decrypter 3.5.1.0 onto the hard drive. I then performed a split dvd by hiding the logos and episodes 2 & 3 which were on a seperate VTS sets to make it fit on a dvd-r. The next step was to export it followed by burning it to a dvd-rw with RecordNow DX 4.50 engine 507. This is the same burning method I use for all my DVDs. At approximately 24 minutes in, the seconds on the time display started doing its dance backwards and forwards as described before on all the players (software and standalones) for approximately 5 minutes. The Tray Player analysis file still shows time errors that do not exist when I use the Menuedit and IfoEdit method. Also, the blanked (hidden) reported times are a lot larger than with the 15 frame blank file I use with menuedit.

http://cdr-zone.com/forum/viewtopic.php?t=1176 DRM is adding an extra second to each cell it replaces at the minute

[Chewy]

That is interesting as it explains why each hidden cell is one second longer than it should be. It also applies to NTSC as well as PAL. That bug may also be the cause of the seconds bouncing around for longer durations with 2.5.3 than prior versions. Ten minutes vs. approx 1-2 minutes for older versions. And here I thought I was just getting better at detecting them.
