TwonkyMedia rescan bug - which TwonkyMedia version installed?

Hi,

the TwonkyMedia version on my MyBook seems to be buggy as it performs rescans after restart even if rescan=0.

How can I find out which version of TwonkyMediaServer is installed on my My Book World
Edition (WDH2NC20000E, firmware 01.01.16) ?

Some people talk about  4.4.9 and 5.1 but the UI of my MyBook looks somewhat different than the screenshots in the WDC support area.

And any ideas how to solve the rescan problem???

Thanks a lot in advance!
