wdtv live does not display image or play flac

i have a wdtv live streaming media player (gen 3) updated to the latest firmware
i am running serviio 1.4 on a centos 6 machine
i compiled the latest version of ffmpeg and have installed version 8.96 of dcraw
I am using the wdtv profile setting on the console for the client
the problem I am having is that files which the wdtv supports are not being served correctly from the serviio server.
the first is a jpeg (4272x2848) that shows up as black on the screen when i try to view it.
the second is a flac file (generated by ffmpeg from m4a file) has the wdtv display an error message about unsupported audio format when I try to play it.
mp3 files play fine on the wdtv via serviio and a smaller 1080x720 version of the file displays fine on the wdtv via serviio
Here is the rub:
when i put the same two files onto a USB stick and play/view them from the stick plugged into the server, they play/view just fine.
when I try to display the large jpeg image on a samsung TV via serviio, it works just fine.
when I try to play the flac or display the jpeg on my various iPhone DLNA clients they work just fine.
Because I can play the flac file via USB, I don't thing that there is a problem with the flac file
Because I can display the image on a samsung via serviio and on the wdtv via USB, i think that the problem is between serviio and the wdtv.
does anyone have any ideas what can be done to solve this? when I get back home, i can gather debugging info - what would be useful in debugging this issue?
