Video always choppy after authoring...

[Lightning_Array]

Whenever I author and burn a DVD from M2V source files that have a top-field frame type, the resulting DVD exibits choppy stand alone DVD Player playback. Reencoding the M2Vs to a frame picture frame type always fixes this but at a loss of quality. Is there a way to change the frame type without reencoding or perhaps another way around this? If not, what would be the best TMPGenc Plus 2.5 settings to use to minimize quality loss from the original M2Vs?

thanks

Where do your m2v files come from ?
If you create them yourself, how, and from what ?
What do you author with ?

The current problem M2V files were demuxed (using rejig or DGIndex) from VOB files that were extracted and split by chapter using DVD Decrypter. DVDAuthorGUI ran into an error while authoring these particular VOBs so I demux them and DVDAuthorGUI outputs a Video_TS folder and I burn it using ImgTool and ImgBurn. That was how I created my newest coaster and I should have known better and checked the frame type before I started authoring. I have run into this same problem using TMPGenc DVD Author and its' burning tool with demuxed Vobs that haven't been split that were extracted from perfectly working DVDs. Its always the same variable (top-field frame type) that creates this problem on my set top DVD player (PS2).

You could try restream or DVD patcher. One or both of these should be able to change the frame order without re-encoding.

Restream will let you toggle between bff and tff but thats not what I'm talking about here. You'll notice that when you open an M2V with restream that right below the "top field first" box is something that reads "Picture structure:" and then it will say something like "top-field" or "frame-picture". It is only when this box reads "top-field" that I have this problem. Checking or unchecking the "top field first" box has no effect on the picture structure, I've tried it and it does not fix the problem. It looks like I will have to reencode.

Have a read of this and see if it fits what you are seeing

What sort of TV do you have ?

[Lightning_Array]

I don't see anything in that article about what could be causing this, maybe I'm missing something. I don't see how my TV could have anything to do with it because I can hear the lens arm motor in my DVD player actuate in time with the skipping and chopping. It sounds like its trying to play a really scratched disk but there are no scrathes on it (obviously).

If the machine is working hard, I'd suspect poor quality media. Have you tried using Nero Speed Disk or DVD Info Pro to scan the disc and check the burn quality ?
