Hi Bobmac...,
I found the same result when playing Absolute 60's via vTuner. If you are in the UK you can use Radiofeeds to find and play Absolute 60's. To this use the front control to go to 'Find Station' >> enter 'abs' as the search clue - gives 7 results >> press NEXT to see these >> scroll to Absolute Radio 60's > press the control to play. You can add the station to a Preset by pressing and holding a number button on the remote.
Alternatively the B2 has an experimental bit of software (it works but doesn't save currently) that allows you to play 'Podcasts', if you know the URL. I found the URL for Absolute 60's by looking at the debug monitor -
Via the web UI type podcast into the search b2 box >> a 'Podcast; box is shown >> type (or copy and paste) the URL into the box >> click on Play. Sometimes it doesn't work first time and plays a track off the HDD. Stop this and go through the podcast and URL stages again.
Although the B2 doesn't store the station URL, the browser (Chrome, etc) remembers so you do not have to enter it each time.
I use this method to listen to alternative streams of stations like Radio Paradise in flac or Radio Caroline in aac.
