O.K., thanks for the report. I have heard the same sort of thing here,
and I suspect that this is due to some change in the newer version of
mplayer. It may be possible to tweak this by altering the buffering
settings or altering the speed setting in cdmp. I will look at this in
my Copious Free Time (tm) *grin*.

Yes, I see these as well, but I think these errors are coming from the
kernel. It may be possible to suppress them by tweaking /etc/sysctl.conf

Lucid has commented this line:
# Uncomment the following to stop low-level messages on console
#kernel.printk = 4 4 1 7

In hardy it was not commented.

Un-commenting this and running 'sudo sysctl -p' might suppress the
low level kernel messages, but I haven't tried it yet, so I could be

Correct. Possibly adding options to the menu for non-usb is worth
doing, although there is a space issue on the bootup screen, which uses
isolinux and not grub (inxusb uses grub).
