Sony BDP-S370 flv H.264 support on Buffalo LS-WXL

I just finally got Serviio 6.0.1 to nicely work on a Buffalo LS-WXL device. However, I have many Flash flv files that I like to play. With the present profile, these files are transcoded and the WXL with its 600 Mhz CPU is severely overtaxed and only processes 10 fps leading to stop and go viewing. FFmpeg reports them as :
Metadata:
aacaot : 2
audiochannels : 2
audiocodecid : mp4a
audiosamplerate : 32000
avclevel : 30
avcprofile : 77
duration : 880
height : 240
moovPosition : 32
videocodecid : avc1
videoframerate : 25
width : 432
However, I discovered that running:
simply remuxes the stream and the player is able to play "out.mp4" perfectly. This seems to imply that a few fixes in the profile should fix this issue permanently. However, I checked out the profiles.xml and am not quite clear how to enable that.
Any help would be greatly appreciated.
