Realplayer (InternetExplorer9, Windows7) video downloads FLV

Hello,

I am helping my father with an issue that seems to be greater than options. He was able to use Realplayer to download video files successfully in the past. Something happened (not sure of the how and why) but it now only downloads video files in FLV format ONLY. I've changed to MP4 and other formats but the output ends up being FLV files. We've tried uninstalling Realplayer, perform registry clean, re-install Realplayer but the result is the same... only FLV files. Anyone else experience this type of issue? I am certain something is corrupt, but figured uninstalling and doing registry cleanup would have resolved any faulty files.

His goal is to use RealPlayer (b/c that's what he knows) do download video clips (YouTube or non YouTube).

Side note... the FLV files when attempting to open with (Default player) RealPlayer... you only get audio, no video and the window is locked (forcing Task Manager to kill RealPlayer session).
