[Chris Walker] “I am encoding at best quality”
How far to the right is the quality slider in the PhotoJPEG compressions setting options?

When people ask for a MOV file they are usually also naively are asking for a square pixel file….usually. Any DV (DVCPRO etc) codec is non-square)
You need to send the file to compressor for the best results and I’d probably choose a frame size of 640×360 (which is a 16:9), square pixel, H.264.

[Bill Kunitz] “they want a .MOV file”
Using what CODEC?
What specific frame size are you choosing for your SD output?
[Bill Kunitz] “I understand that to get 16:9 it will be letterboxed but I can’t even get that.”
It doesn’t have to be.
What application are you using to do this transcoding?

Please read the post at the top of this forum by Craig about how to get the best advice.

[Chris Blair] “A quick google search turned up this link to a similar fix for a DVD playback problem. It’s a two year old link but it was a driver update that fixed DVD playback functionality:
https://docs.info.apple.com/article.html?artnum=120319 “
This fixed an issue where certain Macs with certain types of DVD mechanisms would not play in slow-mo properly and was for a version of OS X that came out in 2002! The update installed some MPEG-2 libraries that were better optimised for Altivec.

[Chris Blair] “I never said it wasn’t a powerful solution. I said DVD’s were originally designed to be played back on hardware DVD players hooked to TVs. The colorspace issues in outputting a DVD for consistent playback and display across computer platforms and monitors is a testament to that. Those issues are non-existent when outputting for NTSC or PAL playback.”
Sorry Chris, but again I have to ask what on earth are you on about? You refer to ‘colorspace issues’ across computer systems, have you not considered that these problems exist across comsumer DVD players and TV sets, if anything, the problems are worse! PAL & NTSC don’t come into it. PAL in a dedicated DVD player is the same PAL on a computer DVD. MPEG-2 is MPEG-2. MPEG-2 decoders adhere to the MPEG-2 decoding standard.
[Chris Blair] “Data rate issues also contribute to inconsistent performance on computers, Mac or PC”
If you re-phrased that to ‘avialable bandwidth issues can contribute to inconsistant performance’ then I’d agree with you. If your computer is saturating all available data buses or the processors are maxed out doing some huge calculations, then problems will occur.
[Chris Blair] “And we’ve seen plenty of Mac computers that have playback issues with DVD Hollywood titles from the video rental store. That’s the first thing we asked the client to do, and their commercial DVD wouldn’t play properly in their Mac either. Once they updated or changed some setting, it worked fine.”
Not in all my years have I seen any issues like this. I would sincerely love to know what they updated or changed to get it working.
[Chris Blair] ”
I’m not sure what I did to you to prompt your negative responses to my posts, but I sure wish you’d stop.”I was prompted by your wild guessing at what the issue maybe, in the process referring to problems with a platform that you clearly have no clue about, assuming that the same problems that can plague PC users would also apply to the Mac platform.
I’m not say that the Mac is without faults, it has many, but only very very rarely do you need to change a setting or update a driver to get something that is part of the OS to perform as advertised.
In my experience, nearly all issues inc media playback have been caused by the installation of crap 3rd party software.
Lastly, I apologise for being negative but I’m the kind of person to call a spade a spade.

How does the Mac handle a commercial DVD title?
Have you tried playing the VOBs on the DVD with VLC on the Mac?
I’ve never had any problems with Prodcoder on anything I’ve tried, it’s a superb application.
Is there something common about the two Macs you’ve tried? (i.e. owned by the same person or company?)

My 10 year old Mac that has never been updated (or cleaned) plays back any DVD I give it, even terribly scratched ones.
My brand new HP work laptop running XP chokes on most DVDs I give it.
[Chris Blair] “Keep in my DVD-videos are designed to be played on hardware DVD players connected to televisions. The fact that you can play them on PCs is a bonus but it requires the DVD-Rom and software to do it.”
What on earth are you on about? A Computer running a piece of software to play back MPEG-2 content from a build in DVD player is 100x more of a powerful solution than a dedicated DVD player. The monitor connected to you computer is usually fair more revealing and detailed than any TV (unless your TV is a FullHD 1920x1080p24 beast – most domestic flat panels run at 1024)
We use dedicated DVD players to test the ‘Lowest common denominator’
[Chris Blair] “-Outdated DVD software player”
The DVD player is part of the OS.
[Chris Blair] “-You used an MPG2 codec that’s new and the Mac software doesn’t decode it well.”
You are grabbing at straws here Chris, see the above.
[Chris Blair] “Your Macs graphic card drivers are outdated.”
Very unlikely to be an issue.
[Chris Blair] “Your DVD software is up to date but using the wrong combination of MPG2 decoder and splitter.”
[Chris Blair] “Your issue is likely an incorrect setting on either you Mac’s DVD hardware or the software DVD player or a combination.”
You clearly have absolutely no clue about the Mac.
The OP should try opening the VOB using VLC.
My guess is that the way the disk was burnt or built on the PC is the reason it’s not playing

[barak Ziv] “key framing every 1 frame”
I think that might be one of your problems. DivX is not an i-frame only format. Generally you’d have this set to 10x your target frame rate, so for 30fps output, you set a keyframe every 300 frames.
