From checking the logilfe you are using PureVision Skin? There is no skinfile for this plugin on this skin yet as far as i know. There are error that some guicontrol could not be found, I'm guessing no gui control can be found. Check if using a different skin (Blue3Wide e.g.) has the same error.
All I'm using is the FLVSplitter from the SAF package. No other Players need to be enabled in MediaPortal Configuration.
