Check project novice question

Hello,
On a Mac 8-core, running Encore CS4, I'm making a BluRay .iso, starting with a 10 Bit uncompressed 1920x1080 Quicktime of a 90-minute feature. Just a bare-bones screening copy; no menus, just "insert and play." When I get to "build", the check project shows "End action not set" and "Title remote not set." Everything under "Menu" is gray, including "Set End Action." I can't find any information about these problems. Can anyone tell me how to fix them, or if I even need to?

Second issue: When I try to burn the BluRay in Toast 10 on the same machine, working from the BDMV/Certificate folders that Encore made, I get the Toast error, "Couldn't set up the track for writing." Could this be from something I'm doing wrong in Encore, or should I be posting this under "Toast?"

thanks
Bruce S
