Make sure you're not in party mode or playing from last.FM, those need fanart support from the client end still.
Sometimes it helps to list the possibilities and then try to narrow it down.
• User error installing the mod (always at the top of any list, we all miss minor details from time to time, no offense intended).
• You're in the wrong mode (last.FM / PartyMode / File mode)
• There's a problem with the mod.
• There's a problem with the fanart files
• There's a problem with the program (how it stores / accesses fanart)
I'm running that mod currently, so unless it has been altered in some way, it should be fine. To be certain, can you copy and paste the contents of the MusicVisualization.xml here in code brackets?
Now let's double check all settings again. The other steps are a pain, you'd be kicking your self if it was a simple oversight in the settings, so lets look again.
Are you installed to the right path (not user roaming)
Windows XP / Windows Vista / Windows 7 (x64 editions)
Code:
\\Program Files(x86)\XBMC\skins\Confluence\
Windows XP / Windows Vista /Windows 7 (X86 editions)
Code:
\\Program Files\XBMC\skins\Confluence\
Next, lets make sure it's not a problem with XBMC it's self (this is the most unlikely case, but easy to rule out). I'm running the Jan 9th build r26660. I can guarantee it works with that. It appears to work fine with the official stable release too. Try one of those.
Now try manual fanart downloads. Go to
HT Backdrops and save a 1920x1080 fanart file for a band as "fanart.jpg" and put it in the artist folder.
While doing that, lets make sure you have the right folder structure.
Code:
Music Folder <- Music shortcut icon goes here (optional)
Artist One <- fanart goes here
Album 1 <- Album cover art goes here
Album 2
Album 3
Artist Two
Album 1
Album 2
Artist Three
Album 1
Album 2
Album 3
Music fanart isn't handled the same as it is with movies ("moviename.avi" + "moviename -fanart.jpg") Proper folder structure and naming are vital. There should only be one fanart image in each folder.
Hope that helps.
