I just found out about the very interesting BDP5500/12. In the leaflet it say it support Ogg Vorbis, which I think is wonderful as I have a few MKV files with vorbis audio. But when I downloaded and looked in the manual, there is no mention of Ogg Vorbis at all. So I wonder if it support Ogg Vorbis or not?
FLAC isn't mentioned anywhere, but it would be very nice if FLAC was supported too. Maybe a future firmware upgrade?
