Track 2:Edit point at bottom field. Possible field reversal?

[TugBoat]

That's what DVDSP says during muxing. I have no idea what it means. I have my suspicions. The resulting 3 track DVD plays fine from the HD, and also from the DVD+R disc using the DVR-105 & 107 in my Mac. Set-Tops are a different story.

Both of my stand-alones have the same problem with the same track, Track 1, not track two as the message says. Track 2 & 3 play perfectly. What I get is the intended track squished into the top half of the screen and part of the menu, partially scrambled, taking up the lower.

Now what's strange is that track one came from 2 AVIs, CD sized, kept separate, encoded separately, and placed end to end in DVDSP. The entire track has this problem, meaning those two separate files are suffering the same aliment. Whatever that may be. Track 2 was encoded the same way as 1, with mpeg2enc. Track 3 was done with ffmpeg. All three are Half DVD.

I thought of using PulldownX to change the fields, just to be doing something, but, these m2vs are half DVD-16:9 and PulldownX says it can't open them. Apparently Half DVDs aren't supported by Pulldown? I just remuxed the same files and got the same error with DVDSP.

Anyone

*****************

It appears that the problem with track 1 and that error message are totally unrelated. I'm now convinced that the error message refers to the chapter markers in track 2 which were behaving strangely. I've re-encoded track 1 but had other problems with it so, not finished yet. I will be back.

What an abortion.
OK, tracks 1&2 are widescreen. So I had to use mpeg2enc to get Half DVD 16:9. I didn't have a single problem with track 1, encoding/muxing/sync.... no problems. Which really makes me wonder why the playback was screwed. The only thing I could do was re-encode. So, I did, a few times. I got the muxer_internal_error the first 2 times. Then I decided to try ffmpeg and use HexEdit to apply my own 16:9 flag. That seems to work, and I think the quality is better also.

Track 2 was a friggin' horror story mainly because the source was an .ogm. ffmpegX failed twice using mpeg2enc. I had to install and use OGMTools to demux it, then try again with ffmpegX. Then mpeg2enc insisted on making a 1':40" video track 1':20". It did this twice. So now, we're up to four consecutive failures with mpeg2enc. I found that by running the Pulldown in ffmpegX the 1':20" track magically became 1':40" and synced up nicely. Unfortunately, I'm fairly certain that's what's giving me the error message in DVDSP

So then I re-encoded track 2 using ffmpeg instead of mpeg2enc and WTF, the first try produced a 1':40" video track. A quick number change with Hex-Edit gave me 16:9, Half DVD. The only problem is you have to interpolate the letterboxing. The 4:3 letterboxing seems to be different that the 16:9. No Problem, Done. And it syncs up nicely with the existing AC3 audio track.

Now I'll reposition the chapters and see how muxing goes.

Well, that fixed it. Re-encoding tracks 1&2 with ffmpeg and using Hex-Edit to get letterboxed Half DVD 16:9. Track 1 displays correctly now and I see no error messages in DVDSP.

...still looking for that 'bangs head against wall' emoticon.
