Twonky 4.4 on Linkstation NAS (mipsel) is broken. It does not see half of the WMA files tags resulting in a lot of WMA files in a UNKNOWN Gneder and Artist categories. Going back to 4.1 fixes the problem which lead me to believe that WMA parser is broken in 4.4... Can you please issue an update as soon as possible? Also, is there a repository of old versions somehwere?
BTW. I have subsitituted file_scanner plugins from 4.4 with version from 4.1 but that would not help. Only reverting twonkyvision core files (twonkymedia and twonkymediaserver) to 4.1 would make a change.
Hope this helps identifying the issue...
