theora - May 2009 - Theora on 1GHz G4 processor

I'd like to convert my DVD collection to Theora, but discovered that my
good old powerbook (1GHz G4) can't keep up with it (tho a 1.2GHz P-III
has no trouble with it): it seems to need a tiny bit more than 100%
of CPU.

I create my video files with Thoggen, at the largest possible size, with
a quality setting of 50%.  And I play them with VLC.

Any hint of what I might want to try to do?  IIUC VLC uses libtheora
which doesn't use AltiVec instructions.  Is there some theora decoder
around that does make better use of my G4?

That is correct. You might try one of the recent 1.1alpha releases of
libtheora. These are a little bit faster, even in C only. Otherwise,
someone would have to implement some of the hotspots in altivec.
