FS-Recorder

I recently discovered FS-Recorder as an alternative to the squirrelly default of FSX.  This one has some really nice features and works well.  I write missions a lot and wanted to show multiple different aircraft landing at KHOU at 10 ninute intervals (real life).  FS Recorder does the trick, BUT it saves files as frc extension, which is incompatible with FSX's "PlayFlightRecordingAction" using fsr files.  Changing the extension doesn't work.  Any ideas or advise are appreciated.  See FS Recorder | FSXMissionsHangar.com if you wish to  check it out for yourself(you'll have to register but it's free)... it's a real professional utility developed by Matthias Neusinger.
