I´m a TeamKodi member as well (so is milhouse ). Generally you are correct and Fernet is the correct person to speak to if it comes to video player related issues. But I don´t want to annoy him with tickets which we (Team LE) can´t reproduce. As already mentioned I couldn´t reproduce any issue while using full DVD structures or DVDs ripped into ISOs. So getting the same structure as the user in question uses could help a lot as I can try to reproduce on LE, Linux, Windows and OSX.
At the top right next to the "search"-symbol there´s a button called "conversations". Click on that and at the pulldown menu you will see some "+" sign to create a new converstation. I´ll PM you and you can answer on that message.
