Network device sees 2 servers

My Netgear MP101 Wireless Media player sometimes finds two servers when only
one copy of the 'Twonkyvision' server and nothing else, is running.
If I do run two servers it will find both - for example, Mediaserver and
Twonkyvision.
The annoying thing is that if it finds two, it then asks which to use and
then needs to
reboot.
Which can happen several times.
I can't find anything on the Netgear site or Twonkyvision's.
Your thoughts would be welcome

TIA
