Needed: Sony BDP-Sx500 profile (S4500)
Here are codecs that are playable with 4500: Part 1: http://kuvapilvi.fi/k/ywsE.jpg and Part2: http://kuvapilvi.fi/k/yws6.jpg
Here are also codecs playable with 4100: Part 1: http://kuvapilvi.fi/k/ywse.jpg Part 2: http://kuvapilvi.fi/k/ywsc.jpg
Difference between 4100 and 4500 is, that the following codecs are added on 4500 (nothing removed)
Video:
-MPEG-1 / MKV
-MPEG-2 / MKV
-MPEG4 / FLV
-VC1 / MKV
-WMV9 / MKV
Audio:
-WMA 10 Pro
-Vorbis
-Monkeys audio
Then there are sidenotes added on 4500:
*7 The player can support WMV9 up to Advance Profile
*10 The player can play AVCHD 3D format
These are only differences I can find.
BDP-S4100 works great with BDP-Sx100 -profile. S4500 almost, but hangs with the mpegts-stream, have to change mpegts to m2ts in the profiles.xml file, when using decoding. .more of it here --> viewtopic.php?f=7&t=22131
So should there be another profile for Sx500-series, you decide.
