Adsense I do not know for sure. I do not use adsense code but have used standard banner link/affiliate code in the past to top or bottom banner area without issue.

Uploading video you need to set the max file size allowed in your admin panel in the ray suite widget area. If you do have this set to more than 8mb's and the number of files per user more than 1 than most likely it is a upload file limit due to your host. Search for .htaccess or php.ini file upload errors in the forums there is a ton see more of fixes that are pretty simple for this one.

Games not sure. What are you using exactally the ray game suite? what version ? This could also be due to the above mentioned .htaccess/php.ini limit. Once increase it could solve your issue.

Sometimes it can be more than this, but file limits .htaccess/php.ini will solve most upload problems, file i/o errors and undefined.
