Maximum execution time exceeded after upgrade to 1.7

After upgrading to 6.x-1.7 I am unable to view nodes that have a video attached to them. I am able to edit the node though.

I am receiving a blank page now after the upgrade & update. Prior to this I was able to view the node and all its content. Every so often when I try to go to the page I receive one of the following errors;

a. A fatal error complaining that the memory limit is too low and needs to be set higher (which is currently set at 96M, so I set it to 512M).
b. A fatal error complaining that the execution time has been exceeded (which was set at 30 seconds, so I set it up to 90 seconds).
c. A blank page (so I added some error_reporting variables in my index.php page which have returned the 2 errors above)

This only happens on nodes that that have a video & image embedded on this content type. And after I set "a" & "b" higher, I recieve "c", the WSOD.

From the "Content -> List" view I can see all my testimonials in which I receive the same error when clicking on the title, however the "edit" button still works and I can go in and edit the node.

When I removed the embedded video (YouTube) from the node and view the node again, it works.

Any help would be greatly appreciated!

Thanks in advanced.
