Everything works exept for the FLV videofile creation

HI there!

Thanks for that superb module. I got it up and almost running :(

I got account @ cirtexhosting, just to play around with FFMPEG, I've never used it before.

I downloaded this:
http://www.jeroenwijering.com/?item=Flash_Video_Player
Flashplayer, and renamed it to Player.swf and uploaded it to /files folder, where videos and thumbnails are created.

After I create new page with drupal (and upload AVI-file with it as an attachment) I run Cron jobs manually and the result is that I'll have thumbnail, but video itself isn't there. I just get that VIDEO CURRENTLY NOT AVAILABLE - message where video should be.

So the thumbnail is in the /files folder, and I also get Flash file named after uploaded video file like "6_videoname.flv", but the filesize is 0.

So something goes wrong when FLV file is created.

My FFMPEG settings in node type page are:

ffmpeg Command:
-i @input -f flv -acodec mp3 -ab 64 -ac 1 @output

ffmpeg Path:
/usr/local/bin/ffmpeg (from Cirtexhosting website FAQ)

I don't get any error messages. I don't know how these files are created. If thumbnail appears and works, can I thing that FFMPEG is working or does it have anything to do with thumbnails?

If I go straight to URL/files/Player.swf, it works. So any Ideas what could be wrong?

Thanks and sorry for the trouble...
