I'm having this error lately. It started 2 or 3 days ago and I can't find any clue to fix it.
Error: 303: Failed to load a resource: cannot access the resource file (try loosening Flash security settings): Error #2048: Security sandbox violation: http://www.espa.tv/player/flowplayer.commercial-3.2.4.swf?0.3325330687 2211397 cannot load data from ://?ttl=1294187993&token=61e159b3e271e55546f1cb994414c021.
This might be a cross domain issue with some of your files. I have a similar problem where I am trying to load streams through Flowplayer's bwcheck and smil pluggins. The smil file has to be on the same domain as the streams otherwise the player will not read the smill file, for example. See these pages:
Still trying to figure this out myself but hopefully this will point you in the right direction.
Oh hey cool no problem. I don't generally post help regarding computers but this particular issue had me stumped and I know many others we're posting at various sights with the same problem when trying to view a Flash video. Also, most people's unsuccessful attempts to fix it seemed to focus on ADOBE FLASH since I was lucky enough to figure out the REAL issue I wanted to save others the time and frustration I had already gone through. After trying all the ADOBE settings, uninstalling, reinstalling etc I finally thought to see if I was having the same issue on my laptop AND desktop and sure enough I was but still I thought well a lot of people are not having a problem at all so what's different? Then I thought how the error message listed a site at the end (something about gorillanation I forget the exact address) and since I was having issues on Cinemassacre.com with a SPRINGBOARD player (at least the loading progress bar says Springboard) I thought to myslef "Wait a minute, sites are blocked / redirected in the HOSTS file! Hmmm I will search the HOSTS file for any Springboard or Gorillanation entries) sure enough my MVP HOSTS file had about three results. After deleting those entries and saving the videos played perfect on my Dessktop and laptop once again. I was happy to share, I also posted where the videos we're posted to as I noticed a couple comments complaining of the same error.
If I don't already have permission to go into the hosts file and see what needs to be removed from /ETC or Terminal, is this the proper way to make hosts file available? http://www.youtube.com/watch?v=oVtYwCwdYUk (not mine, just making sure it's safe to try)
That link is for MAC users. Are you on a MAC? If you are on PC what OS are you running (XP / VISTA / Windows 7) I know only Windows PC platform. If your using Windows I believe you must be logged in as ADMIN to edit your HOSTS file. Sorry, I do not know any other way, those permissions are required for securtiy otherwise anyone/ anything could alter your HOSTS file. I right click NOTEPAD and as mentioned above select "RUN AS ADMINISTRATOR" then load HOSTS file by browsing to the location in Notepad. The RUN AS ADMINISTRATOR OPTION will NOT appear is attempting to open NOTEPAD in start menu or other shortcut, you MUST right click the actual Notepad.exe located in C:\Windows\System32\Notepad.
