Have you considered how poor the MPEG encode wil look anyway for 2 hours of content on a single layer DVD?
Your looking at around 3.3Mbps for the video if you use 129Kbps audio. Thats going to look pretty awful anyway.
60 mins on a single layer DVD is ok. 90 at a push. 120 and its not going to look great.
Also I wouldn't export a reference file. I'd do a full QT export to a fixed resolution. A reference file is neededing to access the source media still and could "break" later.

I've done 2 hours on a single layer disk and had it look fine. There was very little in the way of fast motion (no cars racing by, no explosions, mostly head and shoulder shots, some podium shots, and various graphics.) For encoding I used a 2-pass encoder, VBR at 8000/3400/1400 and PCM audio (1536 kb/s). There were no artifacts or apparent noise.
Of course, if you're trying to encode something like a fast moving sports video, this probably won't come out well. So the content has a lot to do with how well it encodes. Note that noisy video takes up a lot of space as the noise is considered as content.
Obviously, given a choice, use a DL disk if that's an option.

I'd always suggest AC3 audio at 128Kbps giving you over 1.3Mbps extra for video.
With DL player compatability becomes more of an issue.
Hi all, checking back.
Still in progress.
The video has a fair amount of soccer on it so I'm going to put it on 2 DVDs.
I outputted a file to have something to give her, and burned it to a DVD. Thankfully there's another day or so to work with which I didn't know I had.
The mixdown was painless. The QT reference file (my first) was not painless so yeah... although I did figure out that although the screen is black everywhere else, it plays in the finder quick look preview.
has anyone ever heard of a 632x478 aspect ratio? (or once in avid, 712x478).
No luck (edited).
I would NEVER have tried this workflow if I knew it was necessary to go to Mars and back to relink the thing. My huge project (due asap) is now offline and I have wasted an entire day with no progress.
Just AMA'd my media back in directly, but most of the subclips are still offline.
Now: 'exception: an error occurred cleaning. mdb file is missing."
What a nightmare.
Good morning all (sort of),
What is the safest way to proceed with the project at this point?
I don't want to fly blind here since the original project seems to have been affected and would be grateful for any safe suggestions. Thank you
Relinked my old project with the low res MXFs. There were a few AMA subclips in teh timeline showing offline. I linked them and they came back online. I was never able to online the proxies, so still working on that. There is this great project done, but after four days I still can't get it out of my editor.
Tomorrow is the deadline to mail this.
