Netgear MP101 cannot connect to Media Server 5.1

[fugeeeee]

Hi all!

When running TMS 5.1 or 5.1.1 on my Windows Home Server I cannot to the server with a Netgear MP101 client. Other clients (tested with an Oxx Alto) seem to work well.
The Netgear does find the server, but connections to it time out. I'm pretty sure it did work with TMS 5.0.
The firewall on the WHS has been disabled for testing.

Does anyone else have this issue? Is there a way I can make it work?

Thanks in advance!

Update: It doesn't work with 5.0 either. The MP101 connects, but the navigation tree behaves strangely and although the albums are shown there are no tracks to play.

Just in case there are other MP101 users having the same problem: It only happens with firmware 1.4.7. Downgrading to 1.3.7 will allow the MP101 to connect again.
