Strange Real player activity

Ive noticed strange entries in my access log presumably from real
player.
They look like

955969306.841 126 210.9.66.181 NONE/400 1632 GET
http://channels.real.com/getlatest.glh?PV=6.0.5.27&OS=WIN&L=en-US,%20en,%20*&LID=1033&ch=120+54+0+0+0&ch=72+39+0+0+0&ch=44+287+0+0+0&ch=52+505+0+0+0&ch=33+393+0+0+0&ch=73+19+0+0+0&ch=98+27+0+0+0&ch94+244+0+0+0&ch=16+478+0+0+0&ch=113+46+0+0+0&ch=51+116+0+0+0&ch=97+108+0+0+0
- NONE/- -

Notice that they dont say TCP hit or miss etc. They just have NONE.
The other odd thing is that they can appear from IP's that are denied
access to the cache.
IE ex customers who are with another ISP but havent changed their
settings cause these entries as well. Obviously, I can firewall these
out, the ACL's should be causing them to get DENIED.

They arent causing any real problems, but they look odd. What can cause
a NONE operation.
