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