the script is also available on PasteBin.be

What's going wrong?
-m

Still not sure what the specific problem is, whether it's a php problem, whether it's the way things are being displayed... but you have a lot of typo's in there that may be changing things from the way you expect to see them.

In your css, for #videotitle, #all, #videodescription and .p the 'height' attribute is missing the letter e.
-m

you see that i get 2 thumbnails :S
that is one of the problems.

and then the limit of description text is not working :S

ps, i fixed
the height typo..

Where is the $item object being created? It's not included in your source up there, so when I run the script locally I get a bunch of undefined errors.
-m

foreach($xml->channel->item as $item) {
$location = "http://youtube.com/rss/global/top_rated.rss";
$contents = file_get_contents($location);
$xml = new SimpleXMLElement($contents);

I stripped a lot of your formatting out to debug this, and this is what I came up with that works just fine (without styles):

PHP Code:


		
			
<?php

$contents = file_get_contents('http://youtube.com/rss/global/top_rated.rss');
$xml      = new SimpleXMLElement($contents);

$rss_count = 0;

$desclimit = 225; // use 0 for no limit

foreach ($xml->channel->item as $item)
{
    $img = preg_replace('/^.*?(<img [^>]+>).*$/is','\1',$item->description); // Uncomment if you need full <img /> tag
    $imgsrc = preg_replace('/^.*?(<img [^>]*?src="([^"]+)"[^>]*>).*$/is','\2',$item->description);
    $tmp_desc = preg_replace('#.*?(<p>.+?</p>).*#is','\1',$item->description);
    $tmp_desc = trim(preg_replace('#(<[^>]+>|http://\S+|www\.\S+\.\S{2,3}\S+)#','',$tmp_desc));

    $linkarray = explode("=",$item->link);

    echo '<a href="',$item->link,'"><img src="http://s2.ytimg.com/vi/',$linkarray[1],'/default.jpg" title="$item->title." style="float: left;" /></a>';
    echo '<h2><a href="',$item->link,'">',$item->title,'</a></h2>';

    echo '<p style="clear: both;">'.((($desclimit != 0) && (strlen($tmp_desc) > $desclimit)) ? substr($tmp_desc,0,$desclimit-3)."..." : $tmp_desc).'</p>';

    $rss_count++;

    if (isset($_GET['limit']) && (int) $_GET['limit'] == $rss_count)
        break;

}

This is just a stripped down version of yours, not my own version. A few things I came across:

You had a few variables you weren't using. $limit and $i, which you do a check on further down, but nowhere do you increment these values or give them a reason to exist. They seemed sad, so I let them go home.
Your post if/else structure to determine the amount of results returned was a little convoluted. I switched it to a simple GET method so you only have to run one check.
Your string replacement routines (preg_replace) were trying to run on $item which doesn't exist outside of the foreach, so I moved them.
Your $desclimit reality check isn't really necessary, you should just add a comment in to the script if you want, that says something along the lines of "If you enter this amount any lower than 45 characters, the description returned will be too short to be readable"... or something.
Finally your description limiter wasn't working because you were echoing $item->description directly, and not $str which is where you were performing the truncate.

delayedinsanity, thank you but you stripped out the functions to let only see the so many items you click for example u press 4 you only see top 4.

i will try fix it my way but thank you for the pointers.

I didn't strip out any functions, just orphaned variables and css.

Either way some of the points still stand... such as your description limit wasn't working because you never sent it to the screen.
-m

why isn't this working.

PHP Code:


		
			
echo '<a href="',$item->link,'"><img src=\"http://s2.ytimg.com/vi/".$linkarray[1]."/default.jpg\" title=\"$item->title.\" /></a>';

Well, you're using "," instead of "." at the beginning with $item->link

i tryed this, but now the $item->title is not working :S

PHP Code:


		
			
echo '<a href="',$item->link,'"><img src="http://s2.ytimg.com/vi/',$linkarray[1],'/default.jpg" title=".$item->title." style="float: left;" /></a>';

i fixed it now :D
just add "'..'"

PHP Code:


		
			
echo '<a href="',$item->link,'"><img src="http://s2.ytimg.com/vi/',$linkarray[1],'/default.jpg" title="'.$item->title.'" style="float: left;" /></a>';
