DVD burned from ISO ok; burn from folder not ok; original file ok

[jlietz]

I'm having trouble understanding the logic in this one...I've been testing Womble's Video Wizard DVD (June release). From a compliant MPEG-2 file I authored a DVD folder using Womble (then burned on another pc.) The resulting VOB's in the folder played flawlessly on the computer. However, when I played the DVD on a set-top player (player A), it was jerky, like the field order was screwed up or something. I played the DVD in an alternate player (player B) and it was fine. So, I used the original compliant MPEG-2 file to author to an ISO with DVD Workshop (then burned on the same pc as before.) The DVD's burned from the ISO played flawlessly on both player A and player B. So, I thought maybe the first set (burned from the DVD folder) may have been defective so I burned from the folder again, with the same results. Anybody have any idea where the problem lies?

If it was with Womble authoring abiltites I would expect the playback issues to show up in the VOB, but they don't. If it was the burner or the burner software, I would expect the playback problems to show up in both the ISO burned DVD's and the DVD folder burned DVD's.

All ideas welcome. Thanks.

Could just be a bad disc. Nothing more complicated than that.

Could be, but I burned 4 copies (Taiyo Yuden), all with the same jerky results on player A, while they all played fine on player B. Which leads to...it could be the DVD player, but the ISO burned discs played fine on both player A and player B.

Is it possible your "compliant MPEG-2" file is not within spec? Some DVD players handle out of spec files differently.

I'm not familiar with Womble's Video Wizard DVD, but it could also be the culprit (or a combination of them both).

I know DVD Workshop uses presets (user chosen) to ensure input files meet dvd specs. So it could be correcting the original files.

Good thought, but no...DVD Workshop did not re-encode either the video or audio when creating the ISO.

Ok, I think I've found the problem. After several different tests, it appears that Video Wizard DVD is the cause of the problem. A DVD authored with Video Wizard DVD does not play correctly on my JVC DR-M10 or DR-M100 (it does play correctly on my Sony DVD player though.) I have authored with Video Wizard DVD from two independent systems with the same results. Meanwhile, the oriiginal mpeg-2 file authored with Workshop is fine on every player I tried it on (inluding the DR-M10 and DR-M100.

Anybody with a DR-M10 or DR-M100 want to try a test and see they have the same problem? (Video Wizard DVD can be downloaded as a free 30 day triial and is fully functional during the trial period.) Also, I think I may have described the playback problem incorrectly in my original post. The audio plays without any apparent flaws, but the video looks like it is skipping a frame or two every few seconds.

Thanks.

I did not even know MPEG Video Wizard could author. I'd never suggest it, if it can.

That is an odd response. You've never used it (didn't even know it existed), but you wouldn't suggest it to anyone? If you've never used it, what do you have against it?

For what its worth, its a good little program (my current problem aside...) if you don't need advanced menus. It suports full AC-3 encoding/decoding, won't re-encode compliant MPEG-2 files (as with the previous version of MPEG Video Wizard), and allows custom chapter placement by adding markers directly to the timeline, or from an external text file. I haven't used any other editor/authoring package that has such a responsive preview window along with precise/quick control over the timeline It easily allows one to manually scan through a file to find scene changes, much quicker and more accurately, than any other software I've tried (MSP 8, DVD Movie Factory, VDub.)

So, anyone with a DR-M10 or DR-M100 willing to test?

Thanks.

FWIW, DVDs that I authored with DVD Movie Factory fail to play in a Panasonic ES20 DVD Recorder, yet play fine in my SONY players.

I also have one SONY DVD player that will not play DVDs authored with my Toshiba DVD Recorder. Other SONYs play them fine.

Many incompatibilities, perhaps.

Because it could not be very advanced, and the program is an editor.

I'm very much against software that has "added features" that are not the primary use for the software. Most of the time such afterthoughts are poorly done and slapped together.

If you want to author, use authoring software. That's my advice.

Not to mention you've already decided it was the source of the problem. I'm not even remotely shocked about it. It's not a piece of authoring software, it's an MPEG editor.

jlietz，

Hi. I have used MPEG Video Wizard DVD for ages. and I have this kind of problems on my PHILIPS DVD Player before. But it's fixed using this June Version. I am sorry cannot help you. You may try to contact with the support of CO. womble.

Begin rant:

lordsmurf, you have helped me with various questions before and I generally value your advice, but your tendency to be presumptuous of your own expertise in all matters gets tiresome. MPEG Video Wizard is an editor. MPEG Video Wizard DVD is a newer, separate piece of software that offers both editing and basic authoring. For someone like me who doesn't need advanced authoring, it has a lot of appeal as the editing and authoring can be accomplished in the same step. If you want to try it out and tell me it sucks you are more than welcome. Until then, you don't really know what you're talking about it.

End rant

Not to mention you've already decided it was the source of the problem.

I am operating under the assumption that it is the source of the problem, but I'm not yet positive (although I test authored on 2 independent systems, they each contain similar software, one of which could be interfering with Womble...) Which is why I've asked for help. If others report similar results I think we've got our answer and I can report this to Womble. Speaking of...

Thanks, that does help. I am already using the June release.
