Hi,
I guess we’re having a language barrier situation.

I do not have Tiny in Revo, I have CKEditor (which I guess they pulled out, possibly to unify the system under Tiny?).
I tried using CKEditor’s Flash icon. I was presented with a screen to choose a file, Browse Server, and this showed the MODx Resource Browser. After looking around for awhile, I managed to find the upload button, and tried to upload an FLV file, it said
"file type not permitted".
I went back to System, System Settings, Filter by Area, File System...
and changed "Uploadable Flash Types" to include FLV. It was ONLY THEN that I found out that this setting apparently needs Flash files to be in assets/flash, which of course is not created during Revo install, so I had to create it.
Then I went back, and was able to upload the FLV file to assets/flash. My test page didn’t play the file, though. Presumably I need to install a player for that. I know how to do that in Evo, but not in Revo. But at least I got the file and code into the page. Maybe that will help you, maybe not.
Good luck.
Good luck, Dave
