I know the issue of connecting Soundbridge to BBC radio stations has been aired several (many?) times, but I am puzzled as to why one of my devices will connect, and the other won't.
I recently bought a Roku M1000 and a Pinnacle M1001 on eBay (having bricked an M1000 by connecting up a power supply the wrong way round!), and both are Ethernet-connected to the same local network. The M1001 happily connects to (e.g.) BBC Radio 2 (using the url http://www.bbc.co.uk/radio/listen/live/r2.asx), whereas the M1000 goes into endless tries with the same url.
Both are on firmware version 3.0.44, so is this down to a hardware difference?
