Just a wee note, AFAIK the builds from the emCORE release page are taken "as they come" from the Rockbox build system from that moment in time.
Builds are made for the iPod Classic, they just aren't linked anywhere from here...You have to know where they are and go digging for them

But yes, Llorean is correct in saying that Freemyipod is the place one *should* be going for support relating to the Classic until it is promoted to Unstable.
Additionally, fleasbaby, it is a very trivial operation even for one who is completely non-savvy in the realms of computing, to set up a development environment in either
Linux or
Windows and compile your own builds of Rockbox.
From there you'll be able to set the antiskip buffer to whatever you want it to be (within the physical limitations of the player, of course).
