Video add on playback not working

Hi there. I have intalled xbmc along with all of the popular add ons and i just cant seem to get any of them to play. Even youtube videos upon selection take me back to the native home screen. I have hulu and icefilms as well which do exactly the same thing. I have really tried to do a lot of research to sort this out myself but am at a loss and don't know what else to do. I have done everything right as far as instalation and jailbreaking goes, making sure to copy all instructions exactly as they are written. I would greatly appreciate any help. Thankyou very much

Welcome to the XBMC forums.

You need to enable debug logging in XBMC, start a video add-on (see note below) and, when it fails, exit XBMC, locate the debug log on your system, upload it to http://www.pastebin.com or http://www.xbmclogs.com and post just the URL link to your uploaded log here with your reply. Without this information, there's no way to know what the problem may be.

Note: Don't select Icefilms as it is not supported here.
