Hi Anthony!
I tried it some hours after I received the hint from Brian I should
retry and some hours before your e-mail below.
I recompiled once more 45 min ago and the problem seems indeed to be
fixed. I will write another e-mail, if I should observe the codec
matching problem again within the next days.
Best regards and thank you
