Hi Pixisticks,
Thank you very much for your long answer:).
In the meantime i got my VEA-TV working in SL and showing the video from my website. It appears that the .flv version of the video is showing better then the .mov or .mp4 version, so i'll stick to that.
Well, that was the good news. The bad news is that i still cannot get the video showing by the Media tab. However, i notice with the .mov and .mp4 version that the screen turns grey, BUT with the .flv version it then turns black and starts downloading the stream with about 7 Mbit/sec, but no picture or sound, so it must be the video player from SL I guess? Or do i need to change some settings in Firestorm? I think in Preferences i did all settings right, but... perhaps not:). Or do I need to download some other viewer?
The movie in SL Knowledgebase makes it look so easy...
