DVD fails - but MPG files OK.

[terrypin]

I'm using MemoriesOnTV to make a DVD from a mixture of JPGs, digicam AVI clips, and a couple of large AVIs made from screen capture with a prog called FRAPS. I've successfully finished other projects with that mix before, in a variety of programs, including MoTV.

But this one fails. After completing editing, the project previews fine, video and sound. But the DVD (run from HD) doesn't play properly. Just a solid green. Same in various players.

However, and I'm hoping this will give the experts a lead - if I change the extension of the main (large) VOB file to MPG (crude I know, but simple and often effective), then that plays fine.

Any idea what can be going on here, and how I might fix it please?

are you just playing the vob files? or are you playing it as a real dvd so you can access menus?

Thanks Baldrick. I'm just playing it in my usual way from the Video_TS folder, by d-clicking the first IFO file. That runs PowerDVD. Which plays a solid green picture. Same if I d-click the VOB.

Since posting I decided to split the original project in two rough halves. I re-rendered the 2nd half - and it plays OK! Am now re-rendering the 1st half. Logically that should be the rubbish half. Then I can halve and halve again until hopefully I isolate the clip causing the problem. That's my cunning plan anyway!

But doesn't the fact that the MPG does play offer some clue please?

Thoughts on this behaviour anyone please?

Specifically:

1) What fault in the DVD would allow a player to play the 'equivalent' MPG file but not the IFO or VOB file?

2) Any significance in the solid, brightish green colour?

1) An error in the authoring process.
2) Sounds like what you'd see if you had a completely covering subtitle with default colors.

What player ?

Software players can play pretty much anything that isn't corrupt, even if it isn't DVD compliant. Some players, such as VLC, have very high tolerances for corruption, and will play partial and incomplete files.

Even standalone players may play some raw mpegs that are not DVD compliant.

The colour issues tend to point this being an encoding problem, and given the mixed bature of your sources, I'm not too surprised.

Thanks. I'm now suspecting some sort of corrupt MP3, but need to do more tests. I arbitrarily dropped the final MP3, which happens to have been edited externally (in GoldWave) to add a fade, and this time it played OK.

guns1inger: Thanks. Associated player is PowerDVD, but as mentioned same happens in all 4 or 5 others I tried. So not a player related issue.
