As TVmaze now provides data to Kodi, there will be a few bugs to iron out.
I obviously made the switch as soon as I heard :)
Here's the first two problems I found around images.
TV Show Posters:
Not sure which poster currently gets transferred in first position, but it's often not the one I would have expected.
Listing the one that's used as the main show image on the page would be a good start.
TV Show Logos:
All logos currently on TVmaze (Show Image Type: Typography) are junk :(
There were converted to JPG during upload but absolutely have to be PNG with transparency to be usable.
The upload needs to be changed to not convert and only allow PNG.
Feel free to use this thread to track all issues around Kodi, probably best to have it all in one place.
