Hi Kev,
You should always start your posts with the moodle version you are running, but I can see that your site is running the new SCORM player so you are running at least 2.0
that pop-up is being generated by your SCORM package - it needs the "parent" window as the "pop-up" window communicates with the "parent" window which contains the SCORM API inside Moodle. so in it's current state you can't launch without the other pages.
But in Moodle 2 there is a "way" to improve this (make sure you're running the latest 2.2Stable code though as older versions don't display the new window option quite as well) - also there is a bug in the tracker that affects the height of the package that will probably go into core sometime in Feb, see MDL-31381 for more info.
If you modify your SCORM package (using your SCORM authoring tool - not Moodle) to open the package in the same window you can get closer to what you need but you need to make a few config changes in Moodle to improve the display.
SCORM in Moodle has an option to open the package in the current window or in a new window - in previous Moodle versions the SCORM api was always loaded in the "parent" window so you couldn't remove it, but in 2.1/2.2 the API now loads in the pop-up window itself, but Moodle still opens both (I have plans to change this a bit sometime soon)
So...
step 1 - modify your SCORM package so that it doesn't load the package in a new window (you will need to ask your SCORM authoring tool vendor if you don't know how to do this - or ask for help in your scorm authoring tools own forums (if they have one)
Step 2 - in the Moodle settings page for your scorm set the option to open in "new window"
step 3 - enter the SCORM and look at the URL that is used to load the SCORM (it will have something like yoursite.com/mod/scorm/player.php?somevars - copy that url and use it as the link to load the SCORM package.
Also have a look at some of the other settings that change how the package is displayed - you can hide/disable the TOC on the left (looks like a good idea as your package doesn't seem to have one)
hope that helps!
