DVD won't play

[Paladin]

Maybe somebody here will know the answer to this:

A little while back, I was experimenting with the two progressive modes on my DVX100B. I shot footage using both 24p and 24pA. Since I am using Premiere Elements 3.0, I had to edit both on a 29.97 timeline. I had no problem doing this and video from both pulldowns played pretty much the same. I even burned DVDs of footage from both pulldowns and the DVDs played perfectly on every DVD player in the house. The DVDs from the 24pA footage seemed to have a bit better image quality, but not by much.

But here is where it gets odd. It just so happened that a short, one-shot movie I shot for my current film class was one of those I shot using 24pA. I edited it and burned it onto a DVD just like the rest and it, too, played perfectly on all my home DVD players. But, today, when I took it to class and my professor tried to play it on the class DVD player, we got a message saying the DVD was dirty or scratched and could not be read. Is it possible that the class player could not play a DVD encoded with the 2:3:3:2 pulldown?

This is not of earth-shaking importance, just a matter of curiosity; something to file away for future reference.

No, not possible. The DVD isn't encoded with any pulldown. It's just a 29.97 DVD.

You just found a player that couldn't play that particular home-burned DVD. Playability is still not 100%.

Yes, that the problem with DVD's they still have not perfected the technology to allow them to play in all makes and models of players yet..........If you where to have the DVD replicated it should play in about 99% of players out there, but even then you will run across a player that won't work. Obviously replication is not a viable option for something like what you are doing, but it is about the best way to make sure the disc will work..........

I have been finding that DVD's I burn will not playback properly on Mac pc's and certain desktop players.........the video will playback normally, but the audio plays back at a higher speed. It's odd.

I didn't think the pulldown sequence had anything to do with it. After all, the DVD is playing interlaced fields that play one after another. Pulldown type shouldn't matter to a DVD player whether those fields are arranged as 2:3 or 2:3:3:2. It's just that we've played stuff from the same burner before and the DVDs played without trouble. This time, it wouldn't. The only thing different was the pulldown type.

In spite of the fact that my current NLE only has a 29.97 timeline, I prefer the 24pA pulldown for a couple of reasons. One, the images seem (to me) to be of slightly better quality. Now, this might just be my imagination, I admit. Two, I do intend to get a better NLE sometime in the next couple of years and I would like to have my footage archived on tape at 24pA so that future edits can utilize the 23.98 timeline.

This thing with the class' DVD player had me wondering, though, if 24pA had anything to do with the problem. I really couldn't see how it could, but I just wanted to be sure.

Oh, and it seems that Premiere Elements 3.0 has the capability of exporting at 23.98fps to file folders or DVDs. I just wonder how it can do that when it only has 29.97fps on the timeline.
