Thanks for your assistance.
1. I have a situation where the Moment will go to the twonky server and find the tracks but the inner wheel of the mood wheel is blank (ie no mood data from the local DLNA collection). Is this therefore a gracenote problem, or a problem with the Moment, or perhaps a problem with the metadata? I haven't got the Moment to reliably get track data from plex yet, so am very interested in your profile.
2. Yes, I'm sure patternplay will work when I get all track data into the Moment... (it used to work until B&O upgraded the Moment software. They've now downgraded it for me, so I'm back to building the database again).
3. Thanks for the tip re the Various Artists. For some reason I thought the twonky server didn't honour the various artists tag.
4. How do you get the iTunes playlists into twonky? I see there's a playlist building capability in plex, but am not sure their playlists are recognised by the Moment.
