The Pioneer website seems to show very little difference between these players. The only differences I can spot are (on the 868), i-link, Hi-Bit conversion, and Legato Link (none of which I can envisage using). The 868 lists something called "Two-Dimensional Resolution Expander Videoscaler" - anyone know what this actually does? Is it worth the extra money? Edit - apologies, just found an earlier thread on this.
