the youtube app is really nice in that you can search easier in a few ways. Overall I prefer the youtube app for viewing youtube videos, but wiimc is pretty fantastic overall, especially for loading videos off my hard drive and every once and a while when I throw a dvd in.
Gosh I wish there was a way for it to integrate that youtube interface into wiimc, and to somehow work the Netflix one too. That would be awesome to have all videos located in one place with the best versions.
While on the subject, does anyone have the latest WiiMC+? Is that something that can be shared? i really want it, but don't know how to compile that stuff, I've tried but failed.
