Hi Francis,

i think it depends which version of Mediaplayer is installed on the Windows PC, see an overview which file format is support by which version of Mediaplayer here <>

Regarding your question about using LC 5.5  on Win: Just try it. If i remember right, i was able to use my LC 5.5 on Win and Mac.
