This is something I struggled with too, so I actually stopped watching them on YouTube, unless I could figure out the Mandarian name first, and if they already had MDL page or not. For the few I did manage to find, it was only because the very start of the video had an image of the poster, or the video thumbnail did, so I would do an image search on it to find the Mandarian title.
You could also try posting the video in the Discussion/Search Drama forum to see if anyone recognizes it or finds info on it.
