I have a ReadyNAS NV+ with arounfd 600 albums on it in FLAC format. It uses Twonky. I ran PerfectTUNES and in the app itself all the album art appears, except for an obscure handful. However, when I run the Linn Kinsky app which controls the Linn streamers, no more album art appears than before - i.e. lots of blanks. In another location I have RipNAS running Asset. Will it work better on that?
