I had planned to use a DVD-DL so I could use a larger file for better image quality, but the idea of a pause at a layer break really bugs me.

Imgburn allows you to select where the layer-break occurs – best set between low-action shots. Or you can split the file itself exactly where you want it to layer-break (obviously, each part must fit to each layer) and select the 1st file for side A and the 2nd file for side B.

It has all the chapter stops, but DVDstyler doesn’t recognize them, instead assigning a break every 10 minutes.

In DVDStyler, you’ll see the default chapters of every 10 minutes. You must change that to your actual chapter stops – starting with “0” as the first chapter.

But, in theory, no problem. Because I can just change those points to match the ones posted by “oojason” here, right?:

Right, enter those numbers (in the format as shown with the default values).

But DVDStyler does offer an option to assign a frame # for a picture instead of the image it defaults to. BUT … I can’t seem to find a simple media player that will give frame #s for MKVs instead of using HH:MM:SS format.

Just do the math of 24 frames per second for your time . .
24 x ( [HH x 60 x 60] + [MM x 60] + [SS] ) = frame number
. . and fine tune several frames at a time.

BTW, what version of DVDStyler are you using?
