the latest firmware of my QNAP TS-219p+ (v3.5.0 Build0816) includes a twonky server version 5.1. This version (and also version 6.x) works perfectly with my TV and media players (Sony TV, TVIX 6700, SONY Blu-ray).
About one month ago, I purchased a Yamaha RX-V2700 receiver via ebay. This receiver is equipped with LAN and is able to communicate with media servers via DLNA (I am afraid I don’t know which version).
The receiver is able to recognize media servers (WMP, Nero, Fuppes, and Twonkymedia) in the connected network. Therefore for all tries the receiver is able to see the different versions of Twonky Servers in the network server list.
1st try:
with twonky server 5.1 - that the receiver lists the interprets, but there are no titles available
2nd try:
after upgrading to twonky server 6.034 - the Yamaha receiver could not list the interprets, only the standard items (pictures, music, video) are listed.
3rd try:

after installing twonky 4.4.17 everything is OK. The receiver recognizes interprets titles and so on.
But is there a possibility to upgrade to a higher version of twonky server (e.g. that versions which will come with the new firmwares), or is the version 4.4.17 the last one which will work.
I hope this is not the truth.
Thanks for any ideas and suggestions
