    DigitalRadioTech,

    as far as the Real streams go, that is reassuring. But, of course, according to your theory, the BBC could cause the Real streams to take ages a-buffering as well.

    The priority-to-DAB argument does not help non-UK listeners, of course. There was a period when the BBC package was available on DAB in Berlin, alternating with the DigitalOne bouquet, but them days is long gone. Reception was terrible anyway - very weak transmission in the L-band, and DAB is now pretty much dead as a dodo in Germany (It is an ex-format... it has ceased to be. Almost, anyway.). DAB+ should start next year, but will probably also be completely messed up. But I digress.

    Perhaps, as a sort of compensation for the lousy bitrates, the BBC could shorten (alot) the buffering time on the non-UK WMA streams? How about it, Mr Cridland?

    Dogmatix - yes, I recall that the BBC and D1 multiplexes were broadcast in Berlin as part of the UK DAB industry's epic failure of trying to get the German broadcasters to follow them in using the 20-year-old DAB system.

    Have you seen any news about whether the German commercial radio groups are going to be involved in the "big bang" relaunch using DAB+ - they pulled out a couple of weeks ago saying that DAB+ wouldn't be economically vialbe and that they wanted receivers to combine broadcast with IP rather than just using broadcast. Should be one hell of a big bang launch if the commercial stations don't support it...

    BTW, can you not receive the BBC's international AAC+ streams? They should be better quality than the WMA streams - or are you listening on a Wi-Fi radio?

    I'll answer my own question:

    Germany won't now be relaunching using DAB+ - for German speakers see:

    www.digitalfernsehen...

    or non-German speakers see: www.wohnort.org/DAB/...

    That puts the cat amongst the pigeons somewhat...

    A group of commercial stations did say that they would pull out of DAB+, but talks are still ongoing. DAB+ has been postponed to next year anyway, and will not start nationwide as previously announced, but in big cities and maybe along important motorways.

    DAB went downhill in Germany mainly due lo a lack of priceworthy radios (especially for cars), use of the L-band (making imported radios unusable for some channels) and weak transmission, making reception difficult.

    And yes, I listen to internet radio on an internet radio, not my PC. I also compute on my PC, not my internet radios, and watch TV on a TV, not a PC. Perhaps I am old-fashioned, but there it is.

    Would you care to tell me the urls for BBC's international AAC+ streams? I am not aware of them.

    All our AAC+ streams are intended for consumption within the BBC iPlayer only. They don't work in anything other than our own EMP. This is so that we can use features specific to Flash Media Server in future.

    In terms of the Windows streams, we are currently evaluating switching the Microsoft "Fast Start" function on, which would dramatically reduce initial buffering. I'm pushing this to be done, and apologies for the slow progress.

    Incidentally, all our streaming servers are run on our behalf by third parties.
