Hello,
Yes Jonah is still around. His username on the forums in Jonahh.
In terms of your question the Custom_1 position has index.php calls that check to see whether an element is published in custom_1. If there is a module in custom_1 it will use the full page overlay options you have specified in the Template Manager > Template specific, whether that would be a video or full page image.
If you aren't using a module in custom_1 then it will use the small menu with the background bar at the top as per the sub pages of our demo.
Changing this functionality would require removing these index.php values that check for whether the custom_1 module is active thus making it appear as the main page on all pages. We do not provide direct coding support as this is a customization but you can look at the index.php coding posted below to see the php statements.
<?php if ($s5_pos_custom_1 == "published" && $s5_custom1_video_url != "" && $browser != "ie9" && $s5_cutom1_video_preloader == "yes") { ?>
<div id="s5_video_preload" style="height:100%;width:100%;position:fixed;z-index:100;text-align:center;">
<div class="s5_video_loader"></div>
</div>
<?php } ?>
<?php if ($s5_pos_custom_1 == "published") { ?>
<div id="s5_custom1_outer_wrap">
