Missing Remote has a nice rundown of the many movie managers available for MS Media Center users. They compare MyMovies, Collectorz, Salami/Meta Browser and YAMMM. I still use DVD Profiler although SageTV has a nice, automated media manager called Batch Metadata Importer that is continually being improved on and integrated in numerous add-ons for SageTV. What do you use to manage movies on your HTPC?
