Hi guys,
I’m new here and just grabed a copy of WiiMC yesterday, absolutely great work! I’m also a software developer for a media/home-network company so I think I could help on the project. Cover arts support, and more generally library-management (instead of simple file access) would be a really great addition to WiiMC, as deadzoro has told going through a large collection of movies without it is quite a hassle.
Now I don’t think that going the indirect way (first supporting meta-files and use PC scraper apps and then only implement live-grabbers) is the most optimal way. My suggestion would be to port an existing lib that does what we want, libvalhalla for example (http://libvalhalla.geexbox.org/), and then directly integrate it into WiiMC by creating the first UI elements, covert display, summary, …
I will look into the project this week-end if I can find some time.
