I´ve manage to do backups of my PAL dvd´s thanks to the great guides posted here by some of you, using the DVD2AVI, CCE process.
But now while trying to do the same with NTSC DVD i´ve found out that most movies on my standalone DVD play very jerky. I´ve tried to read the guides on Force FIlm, IVTC and deinterlacing but I havent manage to understand what to do. How will I create a .avi file that after treated with CCE and burned on my DVD player wont play with jerky movement.
I already know how to read the information that DVD2AVI gives but i dont know what to do with it. I´ve found that the guides that i saw where very confusing to me.
Can anyone help me with this by telling me how to create a .avi file that will turn my jerky DVD player into a smooth DVD player :)
Please help me because i´me becoming a tad CRAZY by not managing to do this.
many tks

Try to be a bit more descriptive with the subject line.
Many forum users will simply skip your post on that fact alone.
I think that this should be posted in the AVI & DVD Players forum also.
Please don't think I'm annoyed or anything.:)
OK, does the NTSC DVD, the actual DVD, play fine in your player?
You shouldn't have to make an intermediate .avi to solve this.
What are the steps you are taking?

the dvd i´m playing is already a backup copy. But on my neighbours stand alone DVD the film works just fine and in mine the image gets really jerky. The process that i was trying to use was one that i use with PAL movies... DVD2AVI, CCE, Maestro.
But my doubt is how will i do a .avi file of this movie using the complicated methods that u talk about here in the forums so that the NTSC film plays correctly in my dvd.

I'm confused. Why are you creating an intermediate .avi file?

If you have a DVD which plays fine in another person's player, but not your own, it may be that either your player or your TV do not support NTSC video. You may check your player at www.vcdhelp.com/dvdplayers for more information.

If you are attempting to create an .avi for playback on PC, just follow any of Doom9's guides, such as his DivX 5 guide.

but both my DVD and TV suport NTSC. I can see another movies in NTSC that i have perfecly well but not this one. My mistaque when i said that i wanted to create a avi file. what i meant was create a d2v file that later will transform in vfapi into avi, but a d2v file that will allow me to work without any problems about that frames stuff.

If the playback of this particular hand-made DVD isn't working properly, then it is likely that it will take some work by hand.

Start by setting Field Operations to none. (Leave "Force FILM" turned off)

Press F5 to start a preview.

1) Is the framerate 29.97? Most likely it will be 29.97 or 23.976. If it is 23.976, this DVD was made from NTSC film content and has already been Inverse Telecined. Do not use Force FILM, nor will you use any other Inverse Telecine procedure, and you should skip to step 3.

2) Do you see FILM, or FILM %? NTSC or NTSC %? Do you see it switch back and forth between Progressive and Interlaced? This may indicate Telecined content. If it shows "FILM" or "FILM 95%" or above, use Force FILM. Otherwise, follow the instructions in www.doom9.org/ivtc-tut.htm to determine if it was telecined.

3) If the content is not telecined, but does show Interlaced, you will have to de-interlace the content.

The frame rate that shows is 29.97 and in teh video type just NTSC. It does not change back and forword from interlaced to progressive.
What should i do.

Ps: i´m sorry for being such a drag.

Do not Force FILM. Your MPEG-2 video stream does not contain the proper flags.

If the preview window shows PROGRESSIVE, then you have progressive frames, and you may proceed with your process, at 29.97fps.

If the content shows INTERLACED, plus you are sure your content originated with a video camera, and not with 24fps film, you can skip a frame-by-frame examination of the content, and merely deinterlace, retaining 29.97fps.

If the content shows INTERLACED and you are not sure of the source, or, if it switches back and forth between PROGRESSIVE and INTERLACED, you must examine a scene with movement to determine if the content is Telecined, as described in the tutorial.

If the content has been Telecined, you will want to perform an Inverse Telecine, which will drop your framerate to 23.976.

If the content shows interlacing rather than Telecining, then you'll want to de-interlace, retaining 29.97fps. However, before deinterlacing, you may want to test "Swap Field Order" in DVD2AVI Field Operations, just to see if that is the cause of the interlacing artifacts, as per the tutorial.
