After some experimentation on various WMA file with different bit rate I discovered the following.
Bit Rate experiment
320 Kbps plays just fine
346 kbps plays choppy
With higher bit rate the choppyness became noticably longer and longer.
My conclusion is that the DNS-323 cannot cecod the higher bit rate WMA file, either by design, by deficient programing, or it may very well be that the processor is simply to slow to process the higher bit rates.
I will conduct further tries with other formats.
