I need to demux video files created with ffmpeg2theora 0.28+svn18147

I have ogminfo v1.5

and getting this error
(ogminfo.c) OGG stream 1 is of an unknown type (bad header?)
(ogminfo.c) OGG stream 2 is of an unknown type (bad header?)
(ogminfo.c) (a1/serial 1092562206) Vorbis audio (channels 2 rate 48000)

Is possible, that ogminfo is older then ffmpeg2theora ? Or what can be the reason?

I need to re-pack my Vorbis + Theora from OGG to MKV. How I can do that, please? (I'm on Mac OS X and have Linuxes and OpenBSDs too)

Thank you,
