Added stations in iRadio connect ... connect ... connect

Dear all,

I have added Jazz FM on 'Added Stations' (128 kbps AAC via vtuner*) on my ND5XS and have assigned it a radio preset. Somewhat annoyingly, when I select the preset (or select the added station directly), the ND5XS often takes _minutes_ with 'connecting' before the music plays. And sometimes it stays in 'connecting' forever (the ND5XS is connected via ethernet, not wifi).

I do not have this problem with my other iRadio stations that I preset directly (without vtuner).

Have any of you come across similar problems with 'Added Stations', please? Or is it just JazzFM? Or just my ND5XS? Also, does the ND5XS go to vtuner each time to find the added URL, or is this looked up once in vtuner and then stored on the ND5XS itsself?

Many thanks for you help,

Stefan

* Note that JazzFM can also be found under 'Jazz', but only as the 96 kbps MP3 stream, this is why I used vtuner, where I can access the 128 kbps AAC stream:
