Its really strange - I am ripping to a remote share, as you say, and that seems to work most of the time for attributes (except as I mentioned to you in another thread a few mins ago).
But when I display the media in the media grid, esp whilst the CD is still in the drive, I see a mixed up set of duplicated tracks. Of course I expect the tracks to be duplicated because the CD is still in the drive. BUT the folder that represents the actual CD has the correct coverart usually. The folder that represents the ripped album does not - so the system knew the correct coverart but didn't apply it to the rip. Within that "album" folder I see duplicate tracks from the share and the CD, and a seemingly random selection of tracks on BOTH have the correct coverart. Sometimes none of the tracks for the ripped version, and other times about 50% of each. Sometimes the same track on CD and mp3 have cover art, sometimes neither, sometimes one and not the other!
I also logged tickets on this yesterday (about 8 actually!) - yes I am using beta3...
There seem to be alsorts of screwing things going on inside the database - lots of instances of MANY copies of the same attribute with the same data being applied to one track or album. Coverart from one popping up somewhere else, etc! I have tried to describe it all in the tickets, but it is very difficult! All seems to start happening when I start ripping - but it is impossible for me to tell at this point if it is the rip script or updatemedia...
