[sorry if this double-sent; I'm running on a wireless network using ipsec=
=20
over udp, and apparently it's losing packets, since gmail was hanging. . .m=
y=20
school's IT administration seems very silly at times]

Interesting -- I only have one other suggession; I was recently rereading=
=20
the handbook section on burning cd's, and it said that it was better to hav=
e=20
.pcm files which don't have the header that .wav files do -- apparently the=
=20
header produces a 'tick' on playback. Have you tried ripping to .pcm files?=
=20
Perhaps oggenc is looking for a nonexistent header.
I also checked the handbook for copying cd's -- you are correct that 2352 i=
s=20
the "magic" blocksize -- I used 64k when ripping an entire (data) cd to cop=
y=20
it.
