Looking at your newsserver I presume you are in the UK.
I have been looking at one of these for Xmas but have been put off by it only having WEP encryption. From Manual
1Radio@AOL is available for USA customers only.
2 RhapsodyTM is available for USA customers only.
3 NapsterTM is available for USA, Canada, and England customers only.
Files downloaded with Napster? are in the Windows Media DRM format. This is a type of copy protection. These files can be played on the DSM-320 if you use the Windows® Media Connect software. This software can only be run on Windows® XP with Service Pack 2 or Windows® XP Media Center Edition. For details on configuring Windows® Media Connect, please refer to page 26 of the manual.
Well I have managed to sort some issues out, as follows... Seems I had a coincidental logon error for the live365 service, which I hadn't realised was case sensitive - now I can access the online stations. However, using the built in 'internet connection test' I still get a failure which leads me to believe either something in my WAP/router is blocking the test process, or the DSM test is flawed. Interestingly when I check for firmware updates (which it did at first power up, out of the box) it merely goes away, then reports latest f/w installed, not 'unable to connect'. So connection case closed, mostly.
As for encrytion I noticed in the set up, that you could omit encrypted wireless if you wanted to. I guess you mention AOL etc as they are advertised with the bundle, and no I have not seen anything there, but the Live365 works ok, though I am still rooting to get a decent set of stations together that are actually accessible (despite being listed..). Seems odd that WMV does not seem supported too.
Audio play from a remote disk store works nicely and photos are ok, but video is not that great and in fact I think the demand of video moving around my LAN caused it to screw up for the first time i can remember. Overall though I still kinda like the kit for audio/radio alone
