Thanks for all your comments, an updated table is given below including SW licences (incomplete):

Video: Ogg Theora(BSD), MPEG-1, VP3, Snow, Dirac, ffv1
Audio: Ogg Vorbis(GPL/BSD), Flac, MP2, wavpack, TTA, Musepack, speex, sonic
Container: Ogg, Matroska(LGPL), Ogg, Nut, MXF(Dirac)
5.1-support: None similar to AC3/DTS so far, most can handle multiple
channels though
Screen resolutions: no problem
Other issues:?

Further comments:
- Which codecs/containers SW implementations are GPL licensed, and which are not. I'm only
interested in GPL (and maybe LGPL) for a mixed HW/SW solution.
- Which codecs/containers are patent-free or openly available (no fees)?
- What about NUT container format? Maybe the developers can give some
input here. Can it be taken seriously? No software implementation exists
yet, right?
-Comparisons wrt complexity, format overhead, ability for a mixed SW/HW
solution etc.

Thanks,
