Thanks a lot for the advice! I will try to export in Flash 6 format (just don't record if it's possible with Flash 8 Pro).
I "fixed" the problem with webtv's and works fine now FOR ME. I visited several webtv's sites and anyone worked properly if the stream is in Microsoft format I'm using Media Player 11. Then I installed the WGAPluginInstall.exe plugin (download from Microsoft site). It's a plugin to optimize download with FF. Now I can see the webtv's without problem.
However, I think there is a lot of people who can't see any webtv's in mms format on the web. ALWAYS the same bad story with M$; incridible bad thing!
The problem came back today. Then I restored Media Player 10 and all work fine. The admin from xe-media told me this is a problem with MP 11. What is your Media Player version guys?
I don't know if I'm off topic now in the member sites forum... sorry for this.
