So far so good with the new updates. The coverart is a lot better now, even though I noticed I still have a problem of albums appearing more than once or not at all (there is a blank area where an album should be. For some reason I can't click the top two left album covers no matter what. For what it's worth, the tracks are ~90% ogg vorbis files.

As for the video thumbnails, I have it scan my mytube directory and most of the flv files thumbnails come up showing black. I believe this is due to the thumbnails being taken too early in the video. The thumbnails should be snapped considerably further into the video.
