This shouldn't be posted under bug reports. It should be under General discussions or something other than this section.

To change how many videos are displayed in each row, just edit the view.tpl file. Under the <div> for “moduleFeatured”, change the portion that reads “mod 2 eq "0"“ to be “mod 4 eq "0"” so that pages display 4 videos across instead of 2.

For changing the max upload size, I just altered my .htaccess file. I presume this is enough to make it as high as you wish, so long as the amount is supported by your host. Of course, I've never actually tested this to see, so I am mostly just assuming that it's working. I have this added in to the top of my .htaccess.

Code:
php_value upload_max_filesize 250M
php_value post_max_size 350M
php_value output_buffering on
php_value max_execution_time 9999
php_value max_input_time 7000
php_value session.gc_maxlifetime 48800
php_value memory_limit 256M
Hopefully that helps get you to your final destination. If you ever have any sports videos, please pop one my way.
