I still use WMC for OTA recording, because I can't find any replacement for the Movie Guide it offers. many WMC replacements offer channel guides, but you can't filter for only movies, as well as sub-categories. However, I've never used WMC for playback, so I can't say for sure what playback speed options are still available. And it may or may not be able to do that with a DVD/Blu Ray. It might be limited to media files (ripped discs, recorded TV).
