On a slightly unrelated note, i keep hitting the following error in liboggz when using the oggz tools on an ogg dirac stream: /home/davidf/project/liboggz/src/liboggz/oggz.c:202: oggz_close: Assertion `oggz_dlist_is_empty(oggz->packet_buffer)' failed. I'll supply an example file tomorrow if that would be of help. Any thoughts? ..david
