TM 5.2.1 on QNAP and Personal Ratings

[psikey]

Just updated my QNAP NAS which was using version 4.13 I think but the latest QNAP release now includes Twonky 5.1.2

I see custom Music tree is now missing but the Advanced tree option now does most of what my custom tree did anyway including the Personal Ratings now seem to work (didn't with 4.13).

Trouble is there isn't a 4 Star group, just 1, 2, 3, then 5 ???

Why is this as I have many 4 Star rated music tracks?

No solution for this ?

Also I have a lot of playlists, some with over 1,000 tracks which worked perfectly with v4 but take ages to create in Twonky 5 and large delay showing them in my PS3/WDTV.
