I think this problem must be being caused by my BLC so I've out it in this forum, but I could be wrong. I have happily been usign my setup for a while now, connected via a BLC which is in V Master mode:

NL Side: Beovision 11-46, in Opt. 2 Beosound Momeent

ML Side: Beosound 9000 Mk2, in Opt. 0 Beosound 5 in Audio Slave mode

I was messing aound with changing the audio options on my Beosound 9000 yesterday (experimenting for a potential new multiroom connection), but when I finished, I put it back to Opt. 0. When I next tried to listen to an audio source however, my TV came on, said 'Connecting' for a moment, and then went back into standby.  Video sources worked fine, but all audio sources caused this behaviour. I switched everything off at the mains to 'reset' it, switching the BLC on only after everything else was switched on. Things improved, but it's not back as it was.  Now, in order to play an audio source via remote, I have to press the source button twice.  If I press CD for example, the TV comes on, but after a moment it says STOPPED (top left).  If I press CD again, it starts playing. This is annoying as I usually control music via a Beo6, which means I have to press the source, then press back to go back to my sources screen, then press the source button again. I can only assume the problem is caused by the BLC, but I did not change any of the settings in the BLC's web interface. Side note - if I start to play a CD by pressing a CD button on the BS9000 directly, that works fine.  It's only when using remote control I am having this issue.
