Well, different needs/desires.

Ogg Vorbis is a lot more expensive to decode, because the standard
libvorbis uses floating point, while (I *believe*) the standard MP3
decoders are fixed point. Or maybe its just that MP3 is cheaper to
decode anyway.

This should be the default, I think.

No. My N800 gets restarted *a lot* more often than my home server. I
realize (assume, anyway) you're just porting the standard Debian packages,
but it is a different environment.
Anyway, good news in your other post about using the tremor lib. I'll
give it a shot.
