Not that I know of.  Just about all the information I know is gathered
there.  The newsgroups sometimes have bits of information, like divx+
and the component cable you can make, that haven't been added to the
website yet (which reminds me, I need to see if I can enable that mode
on the adv7175a).

Some of his postings had a valid from address (I didn't receive a
bounced message).

It frightens me.  I don't read them too often though, just every once in
a while when I remember they exist.
