When I choose to convert DVDs to mkvs using the generic conversion tool, the resulting mkvs are always unplayable. Zoomplayer throws up an error saying that no such codec exists.
However, exporting to MP4’s and then remuxing them to MKVs using MKVmergeGUI gives me perfectly playable MKVs every time. I’d like to not have to go through this extra step each time if possible. Let me know if you need any more information. I’ll be happy to provide it, if it helps to fix the problem.
