Did Madman Field Blend the Remastered G1 DVDs?

[DELTAprime]

So while we are on the topic. I have a MKV I made of season 1 disk 1 of Madman's Remastered set. How do I change the aspect ratio from 16:9 to 4:3 as it should be and then split the file up into episodes?

16:9? It's one of those is it. DVD's store aspect ratios in two places, one set is stored in the IFO files, which is what every DVD player on earth will read obey, the other place is in the MPEG2 stream itself, which DVD players simply ignore. Most of the time the stream AR matches the AR in the IFO, but since it's redundant information it doesn't have to. Of course MakeMKV removes the actual streams from the VOBs and leaves the IFO files behind so what you end up with is a file with the stream AR which is sometimes wrong.

Either of these should be able to modify the AR in the stream. They're old programs so they may not work very well with modern MKVs, so you'll need to use MKVExtract (MKVCleaver/gMKVExtractGUI) to extract the video as an m2v first then run the programs on the m2v files. That should fix the AR issue. After that you need to remux the video back into the file using MKVMerge. Make sure when you remux the file you set the video's aspect ratio to 4:3 (768, 576) because like a DVD an MKV stores it's ARs in two places.

If you want to split the file the easiest way is to use MKVMerge GUI (MMG), load the file into it, then switch to the Global Tab, choose Split Mode -> Split Before Chapters and enter the chapter numbers you want to split at. Assuming they haven't been renamed you should be able to see the chapter numbers by looking at the file using MediaInfo or Loading the file into the MMG chapter editor.
