Well on P133 non-MMX the xmms oggvorbis plugin it can't do continuous playback (you
get scratched plays at slow motion)
at least with ISA sound card. But consider also that oggvorbis is quite new, while MP3
had several X86 asm replacement
and
optmizations due to many years of development, so maybe it is expected this also into
oggvorbis.
