It very much looks like it.

Here (on Debian) they play just fine; both inside firefox and the
downloaded file with mplayer.

The totem /no-sound/ issue may be because you did not install the
"gstreamer-vorbis" package or it's because of your audio-setup; check
with `gstreamer-properties` to make a test-sound.

..and maybe you did compile mplayer without ogg/theora/vorbis support?!
(install libtheora-dev and libvorbis-dev before compiling it, or simply
use a binary package for mplayer)

try `mplayer -ao jack xxx.ogv`

It should print sth. like this:

Ogg stream 0 is of an unknown type
[Ogg] stream 1: video (Theora v3.2.1), -vid 0
[Ogg] stream 2: audio (Vorbis), -aid 0
