I use only folder.jpg files for cover art. Each CD I store in a separate folder. For double albums the foldername of the first CD ends with CD1 of the second CD2.
The id3v1 album name tag also ends with CD1/CD2 in this case.
Reported this bug under music here:
http://forum.team-mediaportal.com/sh...54&postcount=3

This bug is there since 0.2.2.0. In 0.2.1.0 this bug did not occur.

Now I had time to investigate the bug and found out under what circumstances the bug occurs. Had a few double CDs where the bug didn't show out. Took a look at the id3 tag of these albums. The album id3 tag didn't end with CD1 but with Disk 1/Disk 2. Then I canged for testing the album id3 tags of a double album that didn't work from "Serenity CD1"/"Serenity CD2" into "Serenity Cd 1"/"Serenity Cd 2" did a rescan of the db and surprise - on now playing the CD cover showed up. Then canged the album id3 tags into "Serenity Cd1"/"Serenity Cd2" rescanned and the cover art still showed up.

Summing up: if the the album id3 tags of double albums end with CD1/CD2 the cover art does not show, when CD is changed into Cd the cover art shows up. The foldername is irrelevant, the bug is only linked to the album id3 tag. This is so very strange but that's the cause. Maybe there is a problem with capital letters in the internal music db.
I really hope this can be fixed - don't want to rename/retag all "CD1"/"CD2" into "Cd1"/"Cd2".

No one could reproduce this?
Could it be a problem of my tagger?
This problem is very anoying and seems to be present since the thumbs cache was introduced in 0.2.2.0
Started to scan my music archive on where the album art (folder.jpg) is not displayed on else the CD1/CD2 problem.
For the album "Guns N' Roses - Use Your Illusion II" the Album art from "Guns N' Roses - The Spaghetti Incident" get's displayed. Changed the II into 2 and the correct album art got displayed.
Another problem: "Booker T. & The MG's - Green Onions" - no album art in NowPlaying -> Canged the artist into "Booker T. & The Mg's" then the cover got displayed.
I would so really much like to fix this problem, or at least get some answer...
Maybe it is the case, that the music db has got limitations and these things cannot be fixed, else renaming some capital letters in the mp3 tags.
Hope that someone can look into this - I could provide sample files and do testing as well.
