Field "Content:Video SWF Tools" in views plays only sound

Hi everybody! I installed the "video" module and "swf tools" to play the converted flv content. When i create the node, video is played, but the size of the player window is to big to display it in the block - named "last video" (it is generated by views module). So i change the "Canvas properties" of Flowplayer in the SWF tools settings in order to fit the size of the block and when i choose the output field "Content:Video SWF Tools" in views in order to display it in the block - the player of the apropriate size is displayed in the block, but it playes only the sound of the video but not the video itself. Please, if somebody know the way out - help...
