Sansa Media Converter freezes at 49% when converting videos - here is a fix

If you are having the dreaded “media converter freezes at 49%” issues with transferring videos onto your Sansa (as I was), try converting the videos to MPEG-1 format first. The Media Converter will convert MPEG-1, but not WMV files (no matter what the SMC help files say). I hope this helps you - it did for me.
