I agree with you about the DVD platform. It's not ideal, but it's included in the package we got for making these videos. It's a Japanese company that's doing this for me and DVD discs are still very much the norm here, so that's what the offer. DVD rental shops still abound in Japan. Blueray, despite being a Japanese company standard never really took off here compared to DVD.
I am going to have the online streaming as well, where I won't have to be concerned about formatting like this. It's just these DVDs that are giving me a headache now.
