Tosha can read tracks from CDs with 2352 byte blocks, for
example VideoCDs. I'm using it sometimes to directly pipe
the data into MpegTV to view VCDs under FreeBSD.
(BTW, tosha can also read standard data tracks with 2048
byte blocks. While dd provides the same functionality,
tosha has a few nice features such as a progress and ETA
display, which might make it preferable over dd.)
