Hello!
I have Joomla 1.5.8 with AllVideos Plugin v2.5.3
{flv} tags are working ok (if files are stored on local server where the site is)
But with {flvremote} tags i have some problems (in Opera, in firefox i think it's OK)... i uploaded the file to remote server, and the file IS there, but i my player i get this error - Video not found MY_URL
didn't find any solution, so i installed flv player from www.longtailvideo.com/
it's the same player as allvideos ;)
and it's working with my file server!
