How to stop unwanted splits in excerpts when using shortcodes for sliders or players

Am using this code in functions.php: Issue with enabling formatting in excerpts in Wordpress

to allow shortcodes, javascript and formatting in the excerpt - works great, thanks.

However, I am also using a slider (slideshow satellite), which breaks if I set my excerpt length too low (the slideshow size is obviously related to its content). Does anyone know a way to keep the excerpt length low but when a post has a player/slider called by shortcode, make sure it finishes the embedded code, no matter how long it is?

Thanks

functions.php:

function better_trim_excerpt($text)
{
$raw_excerpt = $text;
if ( '' == $text ) {
    $text = get_the_content('');
    //$text = strip_shortcodes( $text );
    $text = apply_filters('the_content', $text);
    $text = str_replace(']]', ']]gt;', $text);


    // Enable formatting in excerpts - Add HTML tags that you want to be parsed in excerpts, default is 55
    //$text = strip_tags($text, 'strongbemiacodekbdimg');

    // Set custom excerpt length - number of words to be shown in excerpts
    $excerpt_length = apply_filters('excerpt_length', 900);

    // Modify excerpt more string at the end from [...] to ...
    $excerpt_more = apply_filters('excerpt_more', ' ' . '...');

    $words = preg_split("/[\n\r\t ]+/", $text, $excerpt_length + 1, PREG_SPLIT_NO_EMPTY);
    if ( count($words)  $excerpt_length ) {
        array_pop($words);
        $text = implode(' ', $words);




        // IMPORTANT! Prevents tags cutoff by excerpt (i.e. unclosed tags) from breaking formatting
        $text = force_balance_tags( $text );

        $text = $text . $excerpt_more;
    } else {
        $text = implode(' ', $words);
    }
}
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt);
}

// Remove the native excerpt function, and replace it with our improved function
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'better_trim_excerpt');
